    From a normal pack of cards, a card is drawn at random. What is the probability of getting a jack or a king?

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

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

    C)         \[\frac{2}{13}\]                               

    D)        \[\frac{1}{13}\]

    Correct Answer: C

    Solution :

    \[n(E)=4+4=8\] \[n(S)=52\] \[\therefore \]\[P(E)=\frac{n(E)}{n(S)}=\frac{8}{52}=\frac{2}{13}\]
