Math Problem Statement
A manufacturer of game controllers is concerned that its controller may be difficult for left-handed users. They set out to find lefties to test. About 13% of the population is left-handed. If they select a sample of 6 customers at random in their stores, what is the probability of each of the outcomes described in parts a through f below? Question content area bottom Part 1 a) The first lefty is the fifth person chosen. The probability is 0.0745. (Round to four decimal places as needed.) Part 2 b) There are some lefties among the 6 people. The probability is 0.5664. (Round to four decimal places as needed.) Part 3 c) The first lefty is the second or third person. The probability is 0.2115. (Round to four decimal places as needed.) Part 4 d) There are exactly 3 lefties in the group. The probability is 0.0289. (Round to four decimal places as needed.) Part 5 e) There are at least 3 lefties in the group. The probability is enter your response here. (Round to four decimal places as needed.)
