Consider a deck consisting of 6 cards, marked 1,2,5,6,9, and 11 respectively. Three of these cards are selected at random. De ne a random variable W by W=the sum of the minimum and the maximum of the resulting numbers, and then compute the probability mass function of W. Then compute and 2. Hint: Consider the outcomes as unordered, then there are 20 outcomes, which can be listed.

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
