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 art majors will be selected?
Do not round your intermediate computations. Round your final answer to three decimal places.

Step-by-step explanation:
Since there are 9 art majors, the probability of the first student being chosen is 9 out of the 29 students total. The second student is being chosen from a sample of 28 students and 8 art majors.
9/29=.31
8/28= .286
.31 x .286=0.089
