In the western United States, there are many dry-land wheat farms that depend on winter snow and spring rain to produce good crops. About45%of the years there is enough moisture to produce a good wheat crop, depending on the region.

Letrbe a random variable that represents the number of good wheat crops inn= 8 years. Suppose the Zimmer farm has reason to believe that at least 4 out of8 yearswill be good. However, they need at least6 goodyears out of8 yearsto survive financially. Compute the probability that the Zimmers will get at least6 goodyears out of 8, given what they believe is true; that is, computeP(6r| 4r).(Round your answer to three decimal places.)
