A policyholder has a two-year auto insurance for his new car. Let X be the number of accidents that the policyholder experiences in one year. You are given: Pr[X = 0] = 0.9 Pr[X = 1] = 0.08 Pr[X = 2] = 0.02 The number of accidents that the policyholder experiences in each year is independent. Given that the policyholder experiences exactly 2 accidents in two years, find the probability that the policyholder experiences at least one accident in each...
