Is X a binomial? b) What is the probability that exactly 4 adults visit their doctor regularly in such group? c) Find the mean and standard deviation for the number of adults that visit their doctor regularly in such group of 12 adults. d) Is it unusual to have 9 or more adults that visit their doctor regularly in such group of 12 adults? Explain.
Let A аnd B be independent events such thаt P(A) = 0.65 аnd P(B) = 0.42. Find P(A оr B).
