Answer 2

To determine the empirical probability that a person who watched videos was a nurse watching contests, we need to find the number of nurses who watched contests and divide it by the total number of people who watched videos. From the table, we see that 23 nurses watched contests, and the total number of people who watched videos is 290.

Thus, the empirical probability that a person who watched videos was a nurse watching contests is:

23/290 = 0.079

Therefore, the answer is (a) 0.079.
