Exercise 5.4. in parts (a)–(d) below, either use the information given to determine the distribution of the random variable, or show that the information given is not sufficient by describing at least two different random variables that satisfy the given condition. (a) x is a random variable such that x(t) = e6t2 when |t| < 2. (b) y is a random variable such that my (t) = 2 2−t for t < 0.5. (c) z is a random variable such that mz(t) = [infinity] for t ≥ 5. (d) w is a random variable such that mw(2) = 2.

What point is the projection of q on a) r b) s c) t

Four airplanes carrying a total of 400 passengersarrive at the detroit airport. the airplanes carry, respectively,50, 80, 110, and 160 passengers.a) one of the 400 passengers is selected uniformly at random.let x denote the number of passengers that were on theairplane carrying the randomly selected passenger. find var(x)for x as given in the problemb) one of the 4 airplane drivers is also selected uniformly atrandom. let y denote the number of passengers on the chosen driver’s airplane. find var(y) for y as given in the problem
