So in this question, we're betting $1 on even numbers, and x is the winning amount.
00:17
So if we lose x equals minus $1, and if we win, then x is going to be, you get the one dollar.
00:40
So you get plus one dollar.
00:43
You get your dollar back and you get another dollar on top of that.
00:48
So what's your probability of losing? so the probability that x is equal to minus 1 is going to be your probability of losing.
01:00
So you will win if it falls on an even slot.
01:07
So that's half of the numbers between 1 and 36.
01:13
So the probability of you winning is half the numbers between 1 and 36.
01:16
Is 18 chances to win, but there are 38 slots total on the board.
01:22
So that's 9 out of 19.
01:24
The probability of losing is going to be the complement, which is 10 out of 19...
