Question 3 The continuous random variables X and Y have joint probability density function defined by fxy(x, y) = {cx-y, 0s x s 3 and 0 s y s2 0, elsewhere a) Find the value of c. b) Find P(0 s X s 1 and 1 sY S 2) c) Find P(0 S Y S 1) d) Find P(Y > X) e) Find P(Y > X and X > Y = 2). Solution: Question 4 X is a random variable with mean 20 and variance 9. a) Write P(X S 15) in terms of the standard normal distribution and use the attached standard normal table to find P(X s 15). b) Write P(15 S X S 20) in terms of the standard normal distribution, and use the attached standard normal table to find P(15 s X s 20). c) If Y is a normal random variable with mean 2 and variance 12, what is the mean and variance of Z = 2X + Y + 3 ? Solution:
