Question

Use the data in the following table, which lists drive-thru order accuracy at popular fast food chains. Assume that orders are randomly selected from those included in the table Drive-thru Restaurant A В с D Order Accurate 323 279 241 125 Order Not Accurate 33 51 40 11 If one order is selected, find 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 Cor an order that is not accurate is (Round to three decimal places as needed) Are the events of selecting an order from Restaurant Cand selecting an inaccurate order disjoint events? The events disjoint because it possible to

Answer 1
