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?
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
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
