Answering the challenge: On ABC TV's "Who Wants to be a Millionaire," to maximize your expected winnings how sure should you be of your answer to the $500,000 question to answer? Somewhere from about 22.5% to about 46.5%, probably closer to the latter. The answer depends on the value of the opportunity to go on to the $1,000,000 question if you get the $500,000 question. Followup challenge: What should your strategy be if the $500,000 question is: "With how much money will you leave here tonight: (A) $32,000 (B) $250,000 (C) $500,000 (D) $1,000,000"?
