How do you find p anb

WebSimply note that P ( A) = P ( A ∩ B) + P ( A ∩ B c), since A ∩ B and A ∩ B c are mutually exclusive events, and their union is A. Hence, P ( A) − P ( A ∩ B) = 0.7 is the answer. Naturally, you would have realized that 0.9375 was the wrong answer. WebP (A B) is conditional probability. P (A B) means the probability that A happens given that B happens, in other words, P (A B) is the probability of A occurring based on the knowledge that B occurs. If the events A and B are independent, P (A B)=P (A), the outcome of B does not influence the outcome of A, so the probability of A occurring doesn ...
