Consider the following probability distribution for x, a discrete random variable. x 0 1 2 3 P(x) 0.1 0 0.7 0.2 Part 1 of 3 Calculate the expected value of x. Is there another name for "expected value"? If so, what is it? The expected value of x is 2. Another name for "expected value" would be "mean" of the random variable. Key: Answers may vary. Part 2 of 3 Calculate the expected value of x. Is there another name for "expected value"? If so, what is it? (a) expected value = 3.1; mean (b) expected value = 2.0; mean (c) expected value = 2.1; mean (d) expected value = 2.0; median
