What is the probability that a student in a college of 650 students in 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?

PsyDAG,
It would help if you proofread your questions before you posted them.
Question is confusing. What are your asking for specifically?

Al,
Multiplicaiton Rule:
P(math and computer)=P(math) *P(computer)
P(math and computer) = 72/650 * 105/650 = 0.018
The probability that a student enrolled at this college is a math and biology major is 0.018
