  B. Strategy A: P(success) =  ; Strategy B: P(success) =

Question 2

This video demonstrates the Monty Hall Problem, named after the host of the game show Let's Make a Deal that originally aired in the 1960s and 1970s. In this show, contestants picked one of three curtains, one of which had a car behind it and the other two had goats. After contestants chose a curtain, Monty Hall showed the contestant what was behind one of the two curtains the contestant had not chosen. Then he offered the contestant the option to switch her choice. The men in the video set up an experiment to compare the two strategies for playing this game. Strategy A is to stick with the original choice. Strategy B is to switch the choice. How many times do the men perform each strategy? That is, how many trials do they perform for each strategy?
 A. 3
  B. 10
  C. 20
  D. 40
