8. The addition law is potentially helpful when we are interested in computing the probability of a. independent events b. the intersection of two events c. the union of two events d. conditional events 9. The sum of the probabilities of two complementary events is a. Zero b. 0.5 c. 0.57 d. 1.0 10. If a dime is tossed four times and comes up tails all four times, the probability of heads on the fifth trial is a. smaller than the probability of tails b. larger than the probability of tails C. 1/2 d. 1/32 11. Given that event E has a probability of 0.31, the probability of the complement of event E a. cannot be determined with the above information b. c. d. can have any value between zero and one 0.69 is 0.31 T 8.
