Consider the experiment of rolling a pair of dice. Suppose that we are interested in the sum of the face values showing on the dice. a. How many sample points are possible? ( Hint: use the counting rule for multiple-step experiments.) b. List the sample points. c. What is the probability of obtaining a value of 7? d. What is the probability of obtaining a value of 9 or greater? e. Because each roll has six possible even values (2, 4, 6, 8, 10, and 12) and only five possible odd values (3, 5, 7, 9, and 11), the dice should show even values more often than odd values. Do you agree with this statement? Explain. f. What method did you use to assign the probabilities requested?

Consider the experiment of rolling a pair of dice. Suppose that we are interested in the sum of the face values showing on the dice.

  1. a. How many sample points are possible? (Hint: use the counting rule for multiple-step experiments.)
  2. b. List the sample points.
  3. c. What is the probability of obtaining a value of 7?
  4. d. What is the probability of obtaining a value of 9 or greater?
  5. e. Because each roll has six possible even values (2, 4, 6, 8, 10, and 12) and only five possible odd values (3, 5, 7, 9, and 11), the dice should show even values more often than odd values. Do you agree with this statement? Explain.
  6. f. What method did you use to assign the probabilities requested?
