    In a club, men are playing the card game. A man named Sanjeev draw a card from a well shuffled deck of cards.
    Based on the above information, give the answer of the following questions:
    Find the probability of getting a king of black colour:

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

    B) \[\frac{1}{12}\]

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

    D) \[\frac{1}{4}\]

    Correct Answer: A

    Solution :

    Total number of possible outcomes =52
    There are 26 black cards, in which 2 black kings.           
    Now, number of black kings = 2
    Favourable outcomes = 2                           
    \[\therefore \] P(getting a king of black colour)                         
    \[=\frac{\text{Favourable outcomes}}{\text{Possible outcomes}}\]
    \[=\frac{2}{52}=\frac{1}{26}\]
    So, option [a] is correct.
