Hello to every person reading this, for someone who has a better understanding of the topic than i do, at the 10:00 minute mark how does he arrive at P(A)= 0.5, P(B)= 0.4, P(C) = 0.1 Thank you in advance

[@subhanalam956]

can u tell me again how did u calculate numbers in 10.06 minutes. p(A) , p(B) etc.

[@anujonthemove]

For confusion at 12:40 one can refer to this video: kzbin.info/www/bejne/mKDbqJKurNmliMU

bro can you explain me in detail how you calculate probability of bow and arrow example???

[@timmcgrew515]

I think the idea is that the probabilities of your hitting the outer ring, middle ring, and bull's-eye are empirically determined. Those probabilities are then multiplied by the given point values for those outcomes -- values that have been set arbitrarily by whoever is doing the scoring -- to give you the expected value of a single shot.

say in more basic terms

[@mariawaqar-g7y]

very difficult to understand

15:05 why is he suddenly talking about "Spades"? i thought this was a dice problem

[@avibhau3852]

8:28: What is theoretical probability? Isn't probability of outcome THEORETICAL only?

Amazing Explanation with exampless, Please start a series on Calculus for Machine Learning

12:41 : The formula seems wrong as for P(12) we see only 1 occurrence. So it should have been P(12).1 and not P(12).12 : Is that correct?

[@aryadubey6802]

I think we are performing numerical outcome here, which is A.P(A)+B.P(B)+C.P(C), here A,B,C are elements of our sample space, in case of die, it the sums, that's why we are doing P(12).12

[@delick01]

For the bow and arrow. The expected value for a single shot. Wouldn't that be A=10, which has 50% probability ?

[@ssoltani22]

That lady in the background is really putting in the work

[@DrStein-jq8yo]

thanks for your contrubution, great video.

[@davethesid8960]

Probability 0 doesn't mean impossible.

[@jhdomino572]

Then what else does it mean?

[@davethesid8960]

@@jhdomino572 Have you studied measure theory?

[@asrorbekomonullayev8012]

That is cool

[@nicorobin7666]

Does Independence mean that they do not intersect?

[@arpitpachori3620]

It means that the change in value of one doesn't affect the other.
