Blood type O A B AB Blood type O A B AB U.S. probability 0.45 0.40 0.11 0.04 China probability 0.35 0.29 0.28 0.08 Choose an American and a Chinese at random, independently of each other. (a) What Is the probability that both have type O blood? (b) What is the probability that both have the same blood type? 2. [-/1 Points] DETAILS YMSSTAT2 6.E.082. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A company retains a psychologist to assess whether job applicants are suited for assembly-line work. The psychologist clasifies applicants as A (well suited), B (marginal), or C (not suited). The company is concerned about event D: an employee leaves the company within a year of being hired. Data on all people hired In the past 5 years give the following probabilities. P(A) = 0.4 P(B) = 0.3 P(C) = 0.3 P(A and D) = 0.1 P(B and D) = 0.1 P(C and D) = 0.2 Sketch a Venn diagram of the events A, B, C, and D and mark on your diagram the probabilities of all combinations of psychological assessment and leaving (or not) within a year. (Do this on paper. Your Instructor may ask you to turn in your work.) What is P(D), the probability that an employee leaves within a year? 3. [-/1 Points] DETAILS YMSSTAT2 6.E.084. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Many conditional probability calculations are just common sense made automatic. For example, 40% of adults belong to health clubs, and 50% of these health club members go to the club at least twice a week. What percent of all adults go to a health club at least twice a week? Write the information in terms of probabilities and use the general multiplication rule. MacBook Air
