Question: Suppose that two random variables X and Y have the joint probability distribution given in the table.
Find the expected values and variances of the random variables X, Y, X + Y and X - Y.

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
