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.\ndrive - thru restaurant\n| | a | b | c | d |\n|--|--|--|--|--|\n| order accurate | 311 | 264 | 233 | 135 |\n| order not accurate | 40 | 53 | 31 | 19 |\nif one order is selected, find the probability of getting food that is not from restaurant a.\nthe probability of getting food that is not from restaurant a is \n(round to three decimal places as needed.)
Answer
Explanation:
Step1: Calculate total number of orders
Total orders = (311 + 40)+(264 + 53)+(233+31)+(135 + 19) = 351+317+264+154 = 1086
Step2: Calculate number of orders from Restaurant A
Orders from Restaurant A = 311 + 40 = 351
Step3: Calculate number of orders not from Restaurant A
Orders not from Restaurant A=1086 - 351 = 735
Step4: Calculate the probability
Probability = $\frac{735}{1086}\approx0.677$
Answer:
0.677
