Exhibit 20-4 Below is a payoff table involving two states of nature and three decision alternatives. Decision States of Nature Alternative s1 s2 A 15   12   B 16   12   C 20   6   The probability of occurrence of s1 = .3. Refer to Exhibit 20-4. The expected value of alternative C is _____.   a. 12.9     b. 13.2     c. 10.2     d. 26

Events A and B are independent. Find the missing probability. 9. P(B) = ? 50 11 ; P(A®) = P(A N B) = 20

Answer the following statements. Two events are if they have no outcomes in common. Two events are if knowing that one event occurs đoes not change the probability of the other event. MacBook Air 888 F4 96 & 4 8 9 E R Y { P D G H J K L V B > mand command option כ ト
