If the production of a specific part for an assembly of components is regarded as a binomial situation where the random variable X represents the number of defective parts in a production run. Suppose the probability of defective in each unit is p. (a) What is the probability of no defectives in a production run of 10 units? (b) Show that the probability of at most one defective in a production run of 20 units is (1−p) 19
(1+19p)
