Quizplus · Accepted Answer

To estimate the probability that a randomly selected member earns at least $90,000, count the number of members earning $90,000 or more and divide by the total number of members. There are 14 members earning at least $90,000 out of 20 members total, so the probability is 14/20 = 0.7.
