Quizplus · Accepted Answer

The probability of selling one car during a week is equal to the proportion of weeks in which the salesman sold one car out of the total number of weeks. In this case, the salesman sold one car in 10 out of 25 weeks, so the probability is 10/25 = 0.40, or 40%. Therefore, the best choice is B.
