a. Explanation In this context, the joint probability distributions of random variables X and Y is given below: f ( x , y ) = c x y , for x = 1 , 2 , 3 ; y = 1 , 2 , 3 The function f ( x, y ) is said to be joint probability distribution if and only if it satisfies the following properties. 1. f ( x , y ) ≥ 0 for all ( x , y ) 2. ∑ x ∑ y ( x , y ) = 1 . 3. P ( X = x , Y = y ) = f ( x , y ) . For any region A in the xy plane, P ( X , Y ∈ A ) = ∑ ∑ A f ( x , y ) b. To determine Find the value of c for the joint probability distributions of X in this context.
