Let X be a discrete random variable with probability mass function p(x) and cumulative distribution function F(x). The values of the cumulative distribution function F(x) are given below: 0, x<0 0.2, 0<x< 1 F(x) = {0.4, 1<x< 2 0.9, 2<x<3 1, 3 <x 2.1 Fill the table of the probability mass function: х 0123 P(x) ABCD
2.1.1 A = [5marks] 2.1.2 B = [5marks] 2.1.3 C = [5marks] 2.1.4 D = [5marks] 2.2 Find the probabilities: 2.2.1 P(X < 2) = [5marks] 2.2.2 P(X > 2) = [5marks] 2.2.3 P(X + 2) = [5marks]
