The probability for event A is 0.3, the probability for event B is 0.6, and the probability of events A or B is 0.8. Why are the events not mutually exclusive? The sum of P(A) and P(B) is less than P(A or B). The product of P(A) and P(B) is less than P(A or B). The product of P(A) and P(B) is not equal to P(A or B). The sum of P(A) and P(B) is not equal to P(A or B).

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
