q15
Let E1, E2, E3 and E4 be events with the following probabilities: P(E1) = 1/4, P(E2) = 2/5, P(E3) = 1/6, P(E4) = 1/5.
E1 and E2 are mutually exclusive events, while E3 and E4 are independent events.
Let,
A = probability of neither E1 nor E2 occurring
B = probability of exactly one of E3 or E4 occurring.
What are the values of A and B?
