    What is the probability of getting a number greater than 2 or an even number in a single throw of a fair die?

    A) \[\frac{1}{3}\]                                   

    B)        \[\frac{2}{3}\]                   

    C)         \[\frac{5}{6}\]                                  

    D)         \[\frac{1}{6}\]                  

    Correct Answer: C

    Solution :

    \[E=\{2,3,4,5,6\}\Rightarrow n(E)=5\] \[S=\{1,2,3,4,5,6\}\Rightarrow n(S)=6\] \[\therefore \]  \[P(E)=\frac{n(E)}{n(S)}=\frac{5}{6}\]
