The proportion of people who respond to a certain mail-order solicitation is a continuous random variable X that has the density function 2(x+2) 5 0 < x < 1, f(x) = |0, elsewhere. Find the probability that more than 1/4 but fewer than 1/2 of the people contacted will respond to this type of solicitation.
