4.) If a binomial experiment has np =10 and n(1- p) = 20, then calculate P(X =1). (Hint: First determine the values of n and p.) 6.) A quality control procedure at a manufacturing plant involves randomly selecting five items and accepting a whole lot of at least four of the five items are in perfect condition. From past experience, 59.049% of whole lots are perfect. In other words, P(X = 5) =.59049. What is the probability that the next lot will be accepted
