A box contains 7 black shirts, 9 blue shirts, 11 black pants, and 13 blue pants. Determine the probability of randomly selecting a black piece of clothing or a pair of pants. Use PIA or B) = P(A) - P(B) - P(A and B) to
explain your answer.

The highest common factor of 132 and 220

How far is x from 5 on a number line?

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
