A fair coin is tossed three times.
00:01
What is the probability of obtaining one head and two tails?
00:06
So I'm going to draw these three tosses.
00:09
That's 1, 2, 3, and I want a head and two tails.
00:14
But then I'll remember that this can happen in more than one way.
00:19
It can be a tail, a head and a tail.
00:22
Then a tail, a tail and a head.
00:25
So all these satisfy the description over here.
00:30
One head, two tails.
00:31
And the probability associated with each of those events is half times half times half, which is one over eight.
00:39
And I have three of them, and the sum is going to be three over eight.
