Question

The CSU system reported the following probabilities for their student body in 2013. The probability of their student being a male between 17 and 19 is P(A) = 0.11. The probability of their student being a female between 20 and 24, P(B) = 0.30. What is P(A and B) given that year? 0.033 0.410

Answer 1

0

Explanation:

P(A) is the probability that their student be male and has age between 17 and 19, and P(B) represents the probability of their student be a female between 20 and 24, P(A and B) is the intersection of these two groups, which means is the probability that their student be, at the same time a male between 17 and 19, and a female between 20 and 24.

Note that it's impossible! These events are disjointed, so the probability that both happen is 0.
