    A card is drawn from a well shuffled pack of cards. The probability of getting a queen of club or king of heart is [MP PET 1988]

    A)                 \[\frac{1}{52}\]    

    B)                 \[\frac{1}{26}\]

    C)                 \[\frac{1}{18}\]    

    D)                 None of these

    Correct Answer: B

    Solution :

               The probability of card to be queen of club is \[\frac{1}{52}\]  and also probability of card to be a king of heart is \[\frac{1}{52}\].                 Both are mutually exclusive events, hence the required probability \[=\frac{1}{52}+\frac{1}{52}=\frac{2}{52}=\frac{1}{26}\].
