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

    Correct Answer: C

    Solution :

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