Quizplus · Accepted Answer

The expected value of x is the sum of the products of each possible value of x and its probability. In this case, the possible values of x are 1, 2, 3, 4, and 5, and the probabilities of these values are 0.1, 0.2, 0.3, 0.2, and 0.2, respectively. Therefore, the expected value of x is (1 * 0.1) + (2 * 0.2) + (3 * 0.3) + (4 * 0.2) + (5 * 0.2) = 24.
