John is watching an old game show on rerun television called Let’s Make a Deal in which you have to choose a prize behind one of two curtains. Behind one of the curtains is a gag prize worth $ 150, and behind the other is a round-the-world trip worth $7,200. The game show has placed a subliminal message on the curtain containing the gag prize, which makes the probability of choosing the gag prize equal to 75 percent. What is the expected value of the selection, and what is the standard deviation of that selection?
