    Two cards are drawn together from a pack of 52 cards.

    The probability that one is a club and one is a diamond?
    A 13/78 Correct Answer Incorrect Answer
    B 1/4 Correct Answer Incorrect Answer
    C 13/102 Correct Answer Incorrect Answer
    D 2/27 Correct Answer Incorrect Answer

    Solution

    Solution: Here, the ‘one-club’ card has to be drawn from 13 club cards. So, its events = 13C1 And ‘one-diamond’ card has to be drawn from 13 diamond cards. So, its events =13C1 So, concerned events =13C1×13C1 Total events (as two cards are to be drawn from 52 cards) = 52C2 So, P(E) =13C1×13C1/52C2= 13/102
