1. Let X be the height of a man and Y the height of his daughter (both in inches). Suppose that the joint probability density function of X and Y is bivariate normal with the following parameters: μX = 71, μY = 60, σX = 3, σY = 2.7, and ρ = 0.45. Find the probability that the height of the daughter, of a man who is 70 inches tall, is at least 59 inches.
