Question

Three points x1, x2, x3 are selected at random on a line l.What is the probability that x2 lies between x1 and x3?

Answer 1

Step-by-step explanation:

Three points X1,X2,X3 are selected randomly from [0,1]. What is the probability that X2 lies between X1 and X3? 2. The joint probability mass function of X and Y is given by p(1,1) = 1 4 , p(1,2) = 1 8 , p(2,1) = 1 2 , p(2,2) = 1 8 .
