In the current first-year class of a community college, all the students come from three local high schools. Schools I, II, and III supply respectively 40%, 50%, and 10% of the students. The failure rate of students is 4%, 2%, and 6%, respectively. 1. What is the probability that a randomly selected student will not fail? 2. Given that a student does not fail, what is the probability that he or she came from school I?
