(2) a test for extrasensory powers (esp) involves asking a person to tell which of 5 shapes (a circle, star, triangle, diamond, or heart) appears on a hidden computer screen. on each trial, the computer is equally likely to select any of the 5 shapes. suppose researchers are testing a person who does not have esp and so is just guessing on each trial. what is the probability that the person guesses the first 4 first shapes incorrectly but gets the fifth correct?
