To compute the beta of Travis Manufacturing’sstock, you need the product of the deviations of Travis’ returns from their mean and the deviations of the market’s returns from their mean. You also need the squares of the deviations of the market’s

12.6 a. RMcan have three values, 0.32, 0.36 or 0.40. The probability that RM takes one of these values is the sum of the joint probabilities of the return pair that include the particular value of RM . For example, if RM is 0.32, RJ will be 0.32, 0.36 or 0.44.The probability that RM is 0.32 and RJ is 0.32 is 0.10. The probability that RM is 0.32 and RJ is 0.36 is 0.06. The probability that RM is 0.32 andRJ is 0.44 is 0.04. The probability that RM is 0.32 is, therefore, 0.10 + 0.06 + 0.04 = 0.20. The same procedure is used to calculate the probability that RM is 0.36 and the probability that RM is 0.40. Remember, the sum of the probability must be one.
