Let X and Y denote the lengths of life, in hours, of two viruses. Suppose that X and Y are random variables with the joint density function: f(х, у) %3D ezez ifx> 0 and y > 0; otherwise. Then a. k =! b. k = c. k= 1 d. k = 2 Question 4: Given the joint density function: (6 — х — у if 0 < x < 2 and 2 < y < 4; f(x,y) = 8 otherwise. The marginal distribution h(y) is: (6-y a. h(y) = if 2 < y< 4; 8 otherwise. (S=Y if 2
