Here in this question asking random variable x has a cumulative distribution function that takes only two values.
00:11
So since the cumulative distribution function take only two values, we come to a conclusion that the random is discrete random variable since x is a discrete random variable so it will have mass point flat the mass point b a 1 a2, a3, so on.
01:41
And the corresponding probabilities be p1, p2, 3, so on, without loss of journality.
02:13
Let we assume a1 less than a2, less than a3, so on.
02:27
Cumulative distribution frequency of x is as follow.
02:36
Probability x less than a1 equals 0.
02:41
Probability x less than a2 equals b1.
02:47
Probability x less than a3 equal b1 plus b2...
