A device runs until either of two components fails, at which time the device stops running. The joint density function of the lifetimes of the two components, in hours, follows. S k(x + y) if to 0< a <6 and 0 sy55 f(x, y) = otherwise Find k so that f is a joint density function. Preview Find probability that the device fails during its first hour of operation. Preview
