TopNewestI have two envelopes, and am told that one of them has twice as much cash as the other. I open Envelope 1 up. Should I stick to it or switch? Wait, but the envelopes are the same. Why is it that I should always switch to Envelope 2?

In a casino game, a random number \(x\) in the interval \((0, 1)\) is generated on a calculator, and I win \(\frac{1}{x}\) dollars. How much should I be willing to pay to play this game?

Player A and Player B are in a 100 meter race. Player A is at the 50 meter mark, walking at \(1\) \(m/s\). Player B is at the 20 meter mark, sprinting at \(10\) \(m/s\). When Player B reaches the 50 meter mark, player A would've covered some distance by then. Then, when Player B reaches that point, Player A would've walked some more, and so on. Therefore, Player B will never catch up with Player A, and lose the race.

I am also interested in #2. I would think the probability would be 50 50.Log in to reply

I think I have an answer to the 4th one A would be moving but will cover less distance than B in the same time interval......... Therefore at some time B will cross A. – Jahnvi Verma · 2 years ago
