The only way you can determine that is if you know you picked the car. We are not told what was picked so you could just as easily say maybe he only did it because you picked a goat. You don't know either way so it is not part of the question.

LOL, I get it! But before you vanish, hear me out: I was in the same boat until I got a financial advisor. Game changer. They helped me build a strategy instead of throwing darts blindfolded. Just saying, sometimes pros know best.

Okay, you’ve sold me on the financial advisor thing, but where do you even find a good one? Google? A friend’s recommendation? I don’t want to end up with someone who’s winging it as much as I am!

There are a handful of CFAs out there. I've experimented with a few over the past years, but I've stuck with Linda Aretha Reeves for some years now, and her performance has been consistently impressive. She’s known in her field-look her up.

Just checked out Linda Aretha Reeves-she’s exactly what I need to finally feel confident about this investing thing. Appreciate the recommendation!

Watched Linda Aretha on a Bloomberg Finance Summit four years ago, and her presentation was phenomenal! Looks like she’s still killing it.

Love the enthusiasm, but slow your roll, spreadsheet king. Starting with a financial advisor might be smarter than diving headfirst into the Wall Street pool. That’s how I got started-my advisor saved me from throwing my cash at flashy ‘sure things.’ Trust me, you’ll thank yourself later.

Okay, fair point on the advisor idea. I know I need one, but how do you even find someone legit? There’s a sea of ‘experts’ out there, and I’d rather not find out the hard way who’s sinking ships instead of building them.

Looked her up, and wow-she seems like exactly what I need to kickstart my financial journey. Appreciate the recommendation!

That would be true if all doors were candidate to be removed from the beginning. But here the rule is that the host cannot eliminate the player's choice, it does not matter if it is wrong or not. It is basically a forced finalist. So only the other had to pass through the filtering process.

no.

The host can never reveal the door you picked (and neither which contains the prize). So from all the started games that you choose #1 you know the eliminated one will come from #2 or #3. But if you group two doors including yours in them, not everytime the eliminated door will come from them, as maybe you grouped yours with which has the prize. In the long run, you would only started picking the winner option is 1 out of 3 attempts, on average. But as the host knows the locations and is never allowed to reveal the prize anyway, he is who ends up leaving it hidden in the other that keeps closed in the 2 out of 3 times that you start failing.

"why not group 1 and three together for that 2/3 chance" Doors 2 & 3 are grouped together because they are the two doors the contestant _didn't pick._ If the contestant picked door #2, then doors 1 & 3 certainly would be grouped together. The doors get grouped together because if either of those doors has the car, that means the host still has it even after revealing a goat. The contestant has one door in their group (and a 1/3 chance of having the car)... the host has two doors in his group (and a 2/3 chance of having the car).

@@RonaldABG this still makes no sense. you are choosing anew between two doors. one has a goat one has a car. i want to understand it.. unless of course.. its bs.. youtube is certainly full of such things.

@@clocksfinle7 Your door has a higher chance of holding a goat because you picked from a pool that has more goats than car. Every time you picked a goat (2/3 odd) you simply wait for the host to do his things, then switch to win a car. That means your odd is 2/3 for winning a car if you switch.

@@clocksfinle7 “KZbin is certainly full of such things” True…. Your reply is living proof of that…. You are not choosing between two doors. You have to pick one door based on your decision what I better for you, and … one door already holds a car more likely than the other…

It is as simple as this: - odds do not transfer anywhere - the door host left closed, had a car behind with 66.6% chance, eve before host open the other door - one of two doors player haven't picked holds a car twice as likely as the door player picked - it is irrelevant what will host do in some other case, since question is asking for this instance only

We don't know anything about what the host does in other games, we are only told what he did in this game. As far as the odds go, do you understand that there is only a 1/3 chance you picked the door with the car? In other words, it is more likely behind one of the two doors you _didn't_ pick.
