Let X denote the reaction time, in seconds, toa 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 a.Verify if itis a valid density function. b.Find P[(X, Y) ∈A], where A = {(x, y) | 0 < x < ½, ¼< y < ½. c.Find the marginal density g(x).
