MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER In the western United States, there are many dry land wheat farms that depend on winter snow and spring rain to produce good crops. About 70% of the years there is enough moisture to produce a good wheat crop, depending on the region. a USE SA (a) Let r be a random variable that represents the number of good wheat crops in n = 8 years. Suppose the Zimmer farm has reason to believe that at least 4 out of 8 years will be good. However, they need at least 6 good years out of 8 years to survive financially. Compute the probability that the Zimmers will get at least 6 good years out of 8, given what they believe is true; that is, compute P(6 s r | 4 s r). (Round your answer to three decimal places.) (b) Let r be a random variable that represents the number of good wheat crops in n = 10 years. Suppose the Montoya farm has reason to believe that at least 6 out of 10 years will be good. However, they need at least 8 good years out of 10 years to survive financially. Compute the probability that the Montoyas will get at least 8 good years out of 10, given what they believe is true; that is, compute P(8 s r | 6 5 r). (Round your answer to three decimal places.)
