Question: Yosem has already flipped a new Massachusetts quarter three times, and each time it has come up heads. He then says to his friend Pablo, "I'll bet you a dollar that the next flip will come up tails." Pablo agrees to the bet. Yosem flips the coin, it comes up tails, and so he collects a dollar from Pablo. Which of the following best described Yosem's action?
a. The first three coin flips clearly showed thatthe Massachusetts quarter is not a "fair" coin. Therefore, Yosem's bet on the coin coming up "tails" was a bad decision.
b. Since any ordinary quarter is "fair," tails was bound to come up eventually. Yosem made a good decision to bet on the next coin flip being tails, and had a good outcome.
c. After observing three heads in a row, Yosem should have bet more that tails would come up next. Betting only one dollar was a bad one because it reduced his winnings.
d. It is not unusual to observe three consecutive heads when flipping coins. Yosem wasjust lucky and got the good outcome.
