Question 715234: I do not know how to set up this problem in a formula way to answer. What is the probability that a student in a college of 650 students is both a math major and a computer science major (assuming these events are independent) if there are 72 math majors and 105 computer science majors?

----
This is an AND problem with independent events.
-----
P(A AND B) = P(A)*P(B)
----
P(math) = 72/650
P(cs) = 105/650
----
P(math ANS cs) = (72/650)(105/650) = 0.0179
