Suppose that 50 sites on a patient might contain lesions. A biopsy selects 8 sites randomly (without replacement).a) What is the minimum number of sites with lesions so that the probability of at least one selected site contains lesions is greater thanor equal to 0.95?n =ib) Rework the above section if the probability of that event is greater than or equal to 0.99.n =i
