Let x denote the reaction time, in seconds, to a certain stimulusand y denote the temperature (F) at which a certain reaction startsto take place. Suppose that two random variables x and y havethe joint density. f(x, y) = {4xy, 0< x < 1, 0 < y < 1 {0, elsewhereFind(a) P(0 <= x <= 1/2 and 1/4 <= y <= 1/2)(b) P(x < y)
