A woman is trapped in a room at the center of a maze. The room has three exits. Exit 1 leads outside the maze after 3 minutes, on average. Exit 2 will bring her back to the same room after 5 minutes. Exit 3 will bring her back to the same room after 7 minutes. Assume that every time she makes a choice, she is equally likely to choose any exit. What is the expected time taken by her to leave the maze

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

Find the value of x. give reasons to justify your solutions! c ∈ ae
