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 El A B C D Order Accurate 315 273 250 121 Order Not Accurate 37 58 31 1 1 If three different orders are selected, find the probability that they are all from Restaurant B. The probability is D. (Round to four decimal places as needed.) View an example | 2 parts remaining X se 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 cluded in the table. Drive-thru Restaurant A B C D Order Accurate 367 255 206 176 Order Not Accurate 45 53 22 28 three different orders are selected, find the probability that they are all from Restaurant A. he probability that the second order is from Restaurant A is affected by whether the first order is from Restaurant A, because the sampling is done without placement. hus, the probability of each order being from Restaurant A will not be the same because the events are dependent. rst, find P(A), the probability that the first order is from Restaurant A. When selecting an order from a restaurant, there are n = 1152 different orders from which to select. ount the number of orders from Restaurant A. here were 412 orders that were from Restaurant A. ivide the number of orders that were from Restaurant A by the total number of orders to calculate the probability of selecting the first order from Restaurant A, unding to five decimal places. P(A) =. 412 1152 = 0.35764 otice that the total number of orders to choose from, 1152, is much larger than the number of orders being selected, 3. Since the sample size is less than 5% o e total, the calculations can be simplified by assuming the events are independentStep by Step Solution
