Question

the joint probability function of two discrete random variable x and y is given by f (x, y) = c (2x+y) ; where x and y can assume all integers such that o<=x <=2 and 0<=y<=3 and f(x, y) =0 otherwise a) find the value of c and b) find p(x>=1, y<=1)​

Answer 1

Answer:

The joint probability function of two discrete r.v's X and Y is given by f(x, y) = c(2x+y), where x and y can assume all integers such that 0 ≤ x ≤2,0 ≤ y ≤ 3 and f(x,y) =0 otherwise. Find E(X), E(Y) , E(XY), E(X2), E(Y2), var(X), var(Y), cov(X, Y) and ϱ.
