    What is the probability of getting an even number when a die is rolled?

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

    B)         \[\frac{1}{36}\]

    C)  \[\frac{1}{2}\]                  

    D)         \[\frac{1}{12}\]

    Correct Answer: C

    Solution :

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