The probability that a card is drawn from a pack of 52 cards will form a pack of 52 cards will be diamond or king being in ?

A. 4/52

B. 4/13

C. 1/52

D. 2/13

Answer : B. 4/13


Explanation:

    Here, n(S) = 52.
    There are 13 cards of diamond (including 1 king) and there are 3 more kings. Let E = event of getting a diamond or a king.

    Then, n(E) = (13 + 3)
    = 16.
    Therefore, P(E) = n(E) / n(S)
    = 16 / 52
    = 4 / 13.
