Answer:
0
Step-by-step 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.
