The probability that at least one of the events \( A \) and \( B \) happens is \( \frac{3}{5} \). Probability of their simultaneous happening is \( \frac{1}{5} \). Value of \( P(\bar{A})+P(\bar{B}) \) is equal to
(A) \( \frac{2}{5} \)
(B) \( \frac{4}{5} \)
(C) \( \frac{6}{5} \)
(D) \( \frac{7}{5} \)
