Again consider the test in question 70. What is the probability that a person taking the test will get eight out of 20 correct? Do you believe that a person who gets eight out of 20 correct has ESP?

Question 70

The following test is given to people who claim to have extrasensory perception

(ESP). Five cards with different shapes on them are hidden from the person. A card is randomly drawn, and the person is then supposed to guess

(or use ESP to determine) the shape on the card. Suppose that this test is administered 10 times with replacement. What is the probability that the subject will get five correct? Do you think getting more than five out of 10 correct supports the subject’s claim to be endowed with ESP?
