Let ' \( A \) ', ' \( B \) ' and ' \( C \) ' be three independent events with \( P(A)=\frac{1}{3}, P(B)=\frac{1}{2} \) and \( P(C)= \) \( \frac{1}{4} \). The probability of exactly 2 of these events occurring, is equal to
(A) \( \frac{1}{4} \)
(B) \( \frac{7}{24} \)
(C) \( \frac{3}{4} \)
(D) \( \frac{17}{24} \)
