Which description of Mary has higher probability?
a. Mary loves to play tennis.
b. Mary loves to play tennis and, during the summer, averages at least a game a week.
Explain your answer. Define the conjunction fallacy. How does it apply here? Assume for the purpose of illustration that the probability that someone loves to play tennis is .2; the probability that someone plays tennis once or more a week during the summer is .1; and the probability of one or the other of these things is .22.
