  • question_answer
    One card is drawn from each of two ordinary packs of 52 cards. The probability that at least one of them is an ace of heart, is

    A)                 \[\frac{103}{2704}\]           

    B)                 \[\frac{1}{2704}\]

    C)                 \[\frac{2}{52}\]    

    D)                 \[\frac{2601}{2704}\]

    Correct Answer: A

    Solution :

               Required probability is \[1-P\] (no ace of heart)                                 \[=1-\frac{51}{52}.\frac{51}{52}=\frac{(52+51)}{52\,.\,52}=\frac{103}{2704}.\]
