Each person in a group of students was identified by year and asked when he or she preferred taking classes: in the morning, afternoon, or evening. The results are shown in the table.

Bot · Answer

There are 19 freshman who preferred morning classes out of a total of 50 students. So the probability is:

P(morning class | freshman) = 19/50 ≈ 0.380

Rounded to the nearest thousandth, the answer is 0.380.
