Question 8Use the data in the following table, which lists drive-thru order accuracyat popular fast food chains. Assume that orders are randomly selectedfrom those included in the table.Drive-thru Restaurant / A/B/C/ DOrder Accurate/ 58 / 43 / 37 / 60Order Not Accurate/ 50 / 59 / 16 / 15If three different orders are selected, find the probability that they are allfrom restaurant B. Assume that the orders are selected withreplacement. Express your answer as a percentage rounded to thenearest hundredth without the % sign.

A professor sees students during regular office hours. Time spent with students follows an exponential dis- tribution with a mean of 10 minutes. Find the probability that a given student spends fewer than 20 minutes with the professor. Find the probability that a given student spends more than 5 minutes with the professor. Find the probability that a given student spends between 10 and 15 minutes with the professor.
