You learn that the probability a freshman will drop out during the current year is .12, the probability a sophomore will drop out during the current year is .08, and the probability a junior will drop out during the current year is .06. For some reason the drop-out rate for seniors was not reported. However, you learn that the dropout probability for all undergraduates is .088. What is the probability that a senior will drop out during the current year?
