Use the data in the following table, which lists drivethru order accuracy at popular fast food chains. Assume that orders are randomly selected from those included in the table. Drive-thru Restaurant D A B C D Order Accurate 319 268 231 126 Order Not Accurate 3? 54 36 18 If one order is selected, nd the probability of getting an order that is not accurate or is from Restaurant C. Are the events of selecting an order that is not accurate and selecting an order from Restaurant C disjoint events? The probability of getting an order from Restaurant C or an order that Is not accurate Is (Round to three decimal places as needed.) Are the events of selecting an order from Restaurant 0 and selecting an inaccurate order disjoint events? The events Y disjoint because it Y possible to V 1' T in an experiment, college students were given either tour quarers or a $1 bill and they could either keep the money or spend it on gum. The results are summarized in the table. Complete parts (a) through (c) below. Purchased Gum Kept the Money D- Students Given Four Quarters 30 15 Students Given a $1 Bill 19 32 a. Find the probability of randomly selecting a student who spent the money. given that the student was given four quarters. The probability is (Round to three decimal places as needed.) b. Find the probability of randome selecting a student who spent the money. given that the student was given a $1 bill. The probability is . (Round to three decimal places as needed.) c. What do the preceding results suggest? O A. A student given a $1 bill is more likely to have spent the money than a student given four quarters. Q B. A student was more likely to be given tour quarters than a $1 bill. O C. A student given four quarters is more likely to have spent the money than a student given a $1 bill. O D. A student was more likely to have spent the money than to have kept the money
