PMF Random variables X and Y have the joint PX,Y (x, y) >-{8/ = 0, c|x+y], x= -2,0, 2; y = -1,0, 1, otherwise.
PMF Random variables X and Y have the joint PX,Y (x, y) >-{8/ = 0, c|x+y], x= -2,0, 2; y = -1,0, 1, otherwise. What is the value of the constant c? What is P[Y X]? What is P[Y = X]? What is P[X < 1]?
Step by Step Solution
There are 3 Steps involved in it
Step: 1
To find the value of the constant c we need to ensure that the sum of the probabilities over all possible values of X and Y is equal to 1 Summing up the joint PMF over all possible values of X and Y w...
