Two events A and B are such that the probability that at least one of them occurs is \( 5 / 6 \) and both of
P them occurring simultaneously is \( 1 / 3 \). If the probability of not occurrence of \( B \) is \( 1 / 2 \) then

W
(A) \( \mathrm{A} \) and \( \mathrm{B} \) are equally likely
(B) \( \mathrm{A} \) and \( \mathrm{B} \) are independent
(C) \( \mathrm{P}(\mathrm{A} / \mathrm{B})=2 / 3 \)
(D) \( 3 P(A)=4 P(B) \)
