Question

A production facility contains two machines that are used to rework items that are initially defective. Let X be the number of hours that the first machine is in use, and let Ybe the number of hours that the second machine is in use, on a randomly chosen day. Assume that X and Yhave joint probability density function given by 3. f(x)-| (x2 + y*) 0<x<1and 0 < y < 1 0 otherwise
