11.       If  P ( A ) = 0.65,   P ( B ) = 0.58, and  P ( A  and  B ) = 0.76, then  P ( A  or  B ) is: a. 1.23 b. 0.47 c. 0.18 d. 0.11 12. The collection of all possible outcomes of an experiment is called:  13. An experiment consists of tossing 3 coins.   The number of possible outcomes in this  experiment is: 14. Which of the following statements is correct given that the events  A  and  B  have nonzero  probabilities? 15. If  A  and  B  are disjoint events, with  P ( A ) = 0.20 and  P ( B ) = 0.30, then  P ( A  and  B ) is: a. 0.50 b. 0.10 c. 0.00 d. 0.06 2

16. If event  A  does not occur, then its complement  C A  will also not occur. T/F 17. Marginal probability is the probability that a given event will occur, with no other events  taken into consideration.  T/F 18. Conditional probability is the probability that an event will occur, given that another event  will also occur. T/F A construction company has submitted bids on two separate state contracts,  A  and  B . The  company feels that it has a 60% chance of winning contract   A , and a 50% chance of  winning contract   B . Furthermore, the company believes that it has an 80% chance of  winning contract  A  given that it wins contract  B . 19. What is the probability that the company will win both contracts? 20.   What is the probability that the company will win at least one of the two contracts?
