2. Suppose that X and Y have a discrete joint distribution for which the joint p.f. is defined as follows: cly - xfor x = -3,

Answer 1

Answer #1

For a valid probability distribution sum of probabilities must be equal to 1. Following table shows the calculations:

For a valid probability distribution 30c must be equal to 1 so

30c = 1

c = 1/30

------------------------------------------

Following are the set of values for which X <= Y :

Therefore,

$13 P(XY) 13c 0.4333 30$
