2. Let X denote the reaction time, in seconds, to a certain stimulus and Y denote the temperature (°F) at which a certain reaction starts to take place. Suppose that two random variables X and Y have the joint density (x² + 2/2/1,0 < x < 1,0 < y < 2, xy f(x, y) = = {x² ++ 3 elsewhere. 0, a. Verify if it is a valid density function. b. Find P[(X, Y) E A], where A = {(x, y) [ 0 1 | X = ¹½). h. Find P(X> ½ Y = 1). i. Determine if the random variables are statistically independent.
