6.3 Binomial and Geometric Distributions Multiple Choice: Type the correct answer after each number, or circle the correct letter (paper). 1) Which of the following random variables is geometric? a. The number of times I have to roll a single die to get two 6s b. The number of cards I deal from a well-shuffled deck of 52 cards to get a heart c. The number of digits I read in a randomly selected row of the random digits table to get a 7 d. The number of 7s in a row of 40 random digits e. The number of 6s I get if I roll a die 10 times 2) A test for extrasensory perception (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 shapes incorrectly but gets the fifth one correct? a. 1/5 b. ( $) + c. ( $ ) ". ( 3 ) d. ( 3 ). (3) *. ( 3 ) e. 4/5
