In a class of 150 students, 60 like music, 110 like sports and 35 like both music
and sports. If one student is selected at random, what is the probability that he
likes sports but not music?

An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. suppose that three parts are inspected and that the classifications are independent. let the random variable x denote the number of parts that are correctly classified. determine the probability mass function of x. round your answers to four decimal places (e.g. 98.7654). x f(x) 0 1 2 3
