This is a probably question and the x was defined as a random variable and the axe is defined as the number of hats.
00:09
Let me just define the x which is the number of head minus the number of tails.
00:18
This is number of tails.
00:21
This is the value of x here and two tosses of fair queen.
00:26
So the n which is two here.
00:29
So what about the number of hat would be? let's find the values.
00:33
The first probability, just two hats comes and zero tails.
00:38
So the result, the x value would be two.
00:41
Or the number of head would be, let's say, one.
00:44
And this is also one, which is also equal to zero here.
00:49
Or the next probability that would be zero.
00:51
If it is zero, that would be two here, which is equal to negative two...
