9) The probability that a college student studies before a test is 0.87. The probability that a student studies before a test and is on the Dean’s List is 0.77. Find the probability that a randomly selected student who studies before a test is also on the Dean’s List. Write your answer as a percent rounded to the nearest hundredth of a percent. Process:p(Dean’s List | studies before a test) = p(both) / p(studies before a test) = 0.77 / 0.87 = Answer: 88.51%
10) There are 500 strawberry drinks, 300 orange drinks, and 200 berry drinks on a supermarket shelf. The probability that Each drink has contains a harmful bacteria is 0.02, 0.03, and 0.01, respectively. If a drink is randomly selected from the shelf and it contains the harmful bacteria, find the probability that it is a berry drink. Write your answer as a percent rounded to the nearest hundredth of a percent. Process: Bayes’ Formula [(200/1000) x (0.01)] / [(200/1000) x 0.01 + (500/1000) x 0.02 + (300/1000) x 0.03] Answer: 9.52%
11) The probability of getting on the Wall of Fame is 0.04. You randomly select 3 people from the class, find the probability that at least one person made the Wall of Fame. Hint: Think complement. Write your answer as a percent rounded to the nearest hundredth of a percent. Process: The complement of at least one person made it is no one made it. Thus p(at least one made it) = 1 – p(no one made it) = 1 – p(no) x p(no) x p(no) = 1 – 0.96 x 0.96 x 0.96 Answer:11.53%
Tiebreaker) The probability of getting on the Wall of Fame is 0.04. You randomly select 3 people from the class, find the probability exactly one person made the Wall of Fame. Sa your answer as a percent rounded to the nearest hundredth of a percent. Answer: 11.06%
