25. Probability question bank (Maths)

\( A \) and \( B \) are two independent events. The probability that both \( A \) and \( B \) occur is \( \dfrac{1}{6} \) and the probability that neither of them occurs is \( \dfrac{1}{3} \). The probability of occurrence of \( A \) is

If \( E \) and \( F \) are two independent events such that \( 0 < P(E) < 1 \) and \( 0 < P(F) < 1 \), then
