I managed to figure this riddle quite quickly... This is the fifth Ted ed riddle I've successfully completed so far.

[@bobonox4233]

@@pvvineet1722 what is the answer to the third question?

[@pvvineet1722]

@@bobonox4233 honestly, i believe that considering we can only use one disc throughout, our best shot in winning is to go with B, and hope that luck favours us in both the rounds, getting a four against A and C disc will do the trick, if C ends up in 1 instead of 5. The second way could be to pick A, in which case our odds of winning might just be a bit more better, considering B and C have greater odds of getting 2 or 1 respectively

[@aaronhodgin7007]

@@bobonox4233 I believe A is slightly favored to win round 3. Multiply each disk's chance of winning in round 1 by their chance of winning round 2. Assuming your opponent will always choose their best option in round 1, odds of winning for each disk are: A (against C) = 51% B (against A) = 44% C (against B) = 22% Multiply by odds of winning round 2: A = 51% x 29% = 14.79% B= 44% x 33% = 14.52% C = 22% x 38% = 8.36% Therefore A is slightly favored over B in round 3!

For the bonus round the chances of winning the entire time: (Assuming your enemy makes the most intelligent decision to combat you each time. Also round one, disk A is best combated by disk C, not B like what was used in the video; I used the proper calculation to give you the worst odds per disc for each round. Also it's so close, that I had to skip rounding.) A: 14.5656% B: 14.6168% C: 14.607684% The winner is B, by a hair. It is fun to note that disk C has odds of winning 38.22% in both rounds.

HAHAHAHHAHAHAHAAHAHHAAAHAHAA

[@raen984]

The bonus question is the nicest of all three: 1st round: There are two possibilities for any disk you pick. Because the opponent is going to pick according to your pick, we are going to consider only the lowest winning odds (the opponent will choose in order to minimize your odds). For A this is 51%. For B this is 44%. For C this is 38.22%. 2nd round: The video explains this well. Just considering the second round, the odds of A winning is 28.56%. For B this is 33.22%. For C this is 38.22%. 3rd round: In order to get the odds of A winning this round, one must multiply A1 and A2, which gives 14.57%. Multiplying B1 and B2 give 14.62%. C1 and C2 give 14.61%. We see that all three disks have incredibly similar odds, with B just barely coming out on top. But the point is that there really is no difference no matter which one you pick. Cool, innit?

[@jamaluddin9158]

Where did round 3 come from?

[@jamaluddin9158]

We're just supposed to carry out the 2 rounds in succession with the same disk right?

[@jamaluddin9158]

Oh i get it now, by round 3 you mean the going through round 1 and round 2 in succession. Indeed this is pretty cool. The people coming up with these puzzles are amazing!

[@ah2190]

Indeed, but as B has a slight edge over the other two, you should go for that and stick with it. But, if it was that you have to face both of them in 1-on-1 matches, with all three of you locked to the same disk, followed by the battle royal with you still locked to the same disk, and you have to win all three matches, then B trumps out. This is because in the case where you have to fight both of the unchosen disks in succession, A has a 28.56% chance of coming out on top after both fights, B has a 27.18% chance and C has only an 18.73% chance. And, as Raen showed, A has the same odds to win the battle royal, B has a 33.22% chance to win and C has a 38.22% chance. Combining these, and A would have an 8.16% chance of winning all three fights, B would have a 9.03% chance and C would have a 7.16% chance of winning. Either way, those two rivals really wanted to rig the odds to be not in your favour.

[@milaaqui]

I think you have to calculate every possibility so the chances add up to 100%. Your first opponent won't pick thinking only about beating you in round 1, their strategy should be the same as yours. This leaves Disk A with ~31% chance of winning, Disk B with ~35% and Disk C with ~33%. Now the odds for Disk B are better.

[@lucasmellor7070]

[@EricAndCats]

i saw them all. Fun fact the eggs are also Featured in the crystal riddle in the background

[@pungfisho6470]

Yeah

[@jeffwei]

For anyone curious, the answer to the third round is disk B. There’s actually two ways to look at this: does your opponent always choose the best disk to beat you in round 1? Or do they calculate the best remaining disk to maximize their odds of winning both rounds? If we consider the first case, then the odds of winning are just multiplied: A: .51 * .2856 = 14.57% B: .44 * .3322 = 14.62% C: .3822 * .3822 = 14.61% So disk B is the best to keep for both rounds with a 14.62% chance of winning. Now consider if the opponent considers that they also have to keep their choice for the battle royale, so they pick based on those odds instead of just the best disk to beat you in the first round. I’ll save you the tedious calculations, but in every case the opponent still picks the same one and the results are the same.

[@squatpump999]

​@Carlos Soprano It's because if you choose Disk C in round 1 the best option to counter it is Disk B (51% chance of summoning level 1 to lose no matter what + ~11% (.22*.49) chance to lose even w the lvl 5 summon)

[@Bloodlf]

At first I calculated the mean result of each disk. Like that B was the best disk as it has a mean expected value of 3.32 which is more than 3 of disk A and 2.96 of disk C. I think the answer for the last riddle is B because with many tries you get the best expected value. But it could also be C if you really need to win each battleroyal and not get the most levels

[@kittyn5222]

It is not a full explanation but you can see the total possible set of combinations is larger than the total set of combinations we are looking at .

[@ray13317]

@@blopszomb6813 You must understand that the sum of these %s are for choosing A1+A2, B1+B2 and C1+C2. Hence the rest of the % would be derived from A1+B2, A1+C2, B1+A2, B1+C2, C1+A2, and finally, C1+B2. Hence the % you see in the comment will not add up to 100%! Hope this makes sense!

[@Twas-RightHere]

For anyone wondering about the final question, you pick B! A has 51% (1st round) x 28.56% (2nd round) = 14.57% chance of winning both rounds. B has 44% (opponent would pick A round 1) x 33.22% = 14.62% chance of winning both rounds. C has 38.22% (opponent would pick B round 1) x 38.22% = 14.61% chance of winning both rounds. Fascinating how any one of the three disks can be made the best choice with such simple rule changes.

[@av.keshavshastry7785]

Edit: This is correct assuming that the opponent is logically good and will choose as you said in 1st round. Since that's not mentioned explicitly, we will have to assume that she has a 50% chance of selecting either of the other 2 disks. In round 1, opponent can pick any one of the 2 disks. A has 0.5×0.51+0.5×0.56=0.535 B wins over C 0.6178 of the times. Hence, if B is selected, 0.5×0.6178+0.5×0.44=0.5289 Similarly with C, 0.4361 Then the rest of the logic is similar as yours.

[@anapaola7241]

[@jpoy21]

@@av.keshavshastry7785 Why is that so? The goal of the tournament is to win, so why not assume that the opponent is going to use the best possible move?

[@jpoy21]

Either way, the odds are definitely stacked against you if you cannot switch.

[@anthonycalderon5519]

Had to scroll way down to find this, but no - THIS IS INCORRECT. They should pick C! The odds of C beating B is 51% x 78% = 39.78%. (It looks like you mistakenly jotted down 38.22% twice). This gives their overall odds to be 39.78% x 38.22% = 15.20%, making C the best chance of winning.

[@supertron6039]

I solved all 3 and it was quite fun! I solved by calculating losses instead which might've complicated things a bit but ended up basically doing the same thing. For round 1: If I pick A, opponent chooses C having better odds and I lose 49% time If I pick B, opponent choose A having better odds and I lose 56% time If I pick C, opponent chooses B having better odds and I lose 61.78% time So we pick A having least chances of a loss. For round 2: If I pick A, either opponents wins and I lose in (44+49)% = 93% time If I pick B and get a 2, I lose automatically... 56% time If I pick B and get a 4, I lose if disk C rolls a 5... 10.78% time So, on choosing B, I lose 66.78% time If I pick C and get a 1, I lose automatically... 51% time If I pick C and get a 5, I lose if disk B rolls a 6... 10.78% time So, on choosing C, I lose 61.78% time So we pick C having least chances of a loss. For round 3: You just check which disk lands you the best win chances. Disk A: (1-49) * (1-93) = 3.57% win chance Disk B: (1-56) * (1-66.78) = 14.61% win chance Disk C: (1-61.78) * (1-61.78) = 14.60% win chance So disk B barely gives us better odds against disk C.
