The probability that a new driver will pass a driving test is 0.8. 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. What is the probability that exactly one of the three will take at least two attempts to pass the test? (Assume independence)
