The probability a new driver will pass a driving test is 0.8. Suppose 3 students take the driving test until each has passed it. a) One student takes the test until she passes it. What is the probability it will take at least two attempts to pass the test? b) Now suppose three students take the driving test until each has passed it. What is the probability that exactly one of the three will take at least two attempts before passing the test? (assume independence)

A driver's license examiner knows that 75% of all applicants have attended a driving school. If an applicant has attended a driving school, the probability that he or she will pass the license exam is 0.85, and if an applicant has not attended a driving school, that probability is 0.60. Suppose it is known that an applicant has passed the exam. What is the conditional probability that he or she has attended a driving school? Note: A numerical answer is required. [4 pts]
