Use the data in the following table, which lists drive-thru order accuracy at popular fast food chains. Assume th randomly selected from those included in the table. Drive-thru Restaurant O A В D Order Accurate 340 272 233 130 Order Not Accurate 38 58 33 19 If one order is selected, find the probability of getting an order that is not accurate or is from Restaurant C. Are selecting an order that is not accurate and selecting an order from Restaurant C disjoint events?

4b) Three board members for a nonprofit organization will be selected from a group of five people. The board members will be selected by drawing names from a hat. The names of the five possible board members are Allison, Betty, Charlie, Dave, and Emily. The possible simple events can be represented as follows: ABC, ABD, ABE, ACD, ACE, ADE, BCD, BCE, BDE, CDE Here, for example, ABC represents the outcome that Allison, Betty, and Charlie are selected to be on board. The events A and B are defined as follows: A= event that Betty and Allison are both selected B = event that Charlie and Dave are both selected Then the events A and B mutually exclusive. True 2 False the

M and Q, N and R, P and Q, Q and R OJ. None

Your friend tells you that when drawing a card from a standard deck, P(Jack or Heart) = P(Jack) + P(Heart). Your friend is…     which one of these answer choices is correct?   a.) Correct, since drawing a Jack and drawing a Heart are disjoint events. b.) Correct, since drawing a Jack and drawing a Heart are independent events. c.) Incorrect, since drawing a Jack and drawing a Heart are not independent events. d.) Incorrect, since drawing a Jack and drawing a Heart are not disjoint events.
