Chapter 4.2, Problem 4.1AE

Use the apple! Random Numbers to generate a list of 25 numbers between 1 and 3, inclusive. Let x represent a number chosen from this list.

1. a. What are the possible values of x?
2. b. Write a probability distribution for x in table form.
3. c. Use the probability distribution in part b to find the expected value of x.
4. d. Let y be a number randomly chosen from the set {1, 2, 3}. Write a probability distribution for y in table form and use it to find the expected value of y.
5. e. Compare the expected values of x and yin parts c and d. Why should these two numbers be approximately the same?
