A university class has 20 students: 10 are history majors, 3

are accounting majors, and 7 are business majors. (Each student has only one of these majors.) The professor is planning to select two of the students for a demonstration. The first student will be selected at random, and then the second student will be selected at random from the remaining students. What is the probability that two accounting majors will be selected?

Do not round your intermediate computations. Round your final answer to three decimal places.
