Kamal and Monika appeared for an interview for two vacancies. The probability of Kamal's selection is 1 3 and that of Monika's selection is 1 5 . Find the probability that both of them will be selected.

Given, Probability of selection of Kamal = P ( K ) = 1 3 Probability of selection of Monika = P ( M ) = 1 5 ∴ P (Both of them selected) = P ( K ∩ M ) = P ( K ) P ( M ) = 1 3 × 1 5 = 1 15 Which is the required probability.
