In the senior year of a high school graduating class of 80 students, 34 studied mathematics, 58 studied psychology, 44 studied history, 16 studied both mathematics and history, 23 studied both mathematics and psychology, 7 studied history but neither mathematics nor psychology, 8 studied all three subjects, and 4 did not take any of the three. If a student who studied mathematics is selected, what is the probability that the student has also studied psychology? [The answer should be a...
1. In a high school class of 100 students, 42 studied mathematics, 68 studied psychology, 54 studied history, 22 studied both mathematics and history, 25 studied both mathematics and psychology, 7 studied history but niether mathematics nor pychology, 10 studied all three subjects, and 8 took none of these. Randomly selecting a student from the class, what is the probability of the following event that: (a) a person enrolled in psychology takes all three subjects. (b) a person not taking...
