Statistics question 2. Twenty percent of all telephones of a certain type are submitted forservice while under warranty. Of these, 60% can be repaired, whereasthe other 40% must be replaced by new units. If a company purchases10 telephones of this type, what is the probability that exactly two willend up being replaced under warranty?3. Let A be the event that a randomly selected college student has takena statistics course, and let B be the event that the student has taken abiology course. Suppose P(A) = 0.4, P(B) = 0.3, and P(AN B) = 0.2.(a) Find the probability that a student has taken neither statisticsnor biology.(b) Find the probability that a student has taken statistics but not
