Hello, this is instructor nicole.

So we're going to calculate the probability of winning for each contestant in this game in which we have an urn that contains four black balls and two white balls.
00:12
So that's how we're going to represent that.
00:14
And if we add these together, we have six total.
00:17
So we're going to need that to calculate our possibilities.
00:21
So let's look at player one.
00:23
So they're going to draw, they need to draw white to win.
00:26
So there's two possibilities of drawing white out of six.
00:29
Six total, giving their probability of one -third or written as a decimal 0 .3.
00:36
Now, the second player is only going to draw if the first player doesn't win, because we're told the game is over when one person draws white, they win the first person to draw white.
00:47
So that means player one must have drawn black because we go on to the second player...
