    Find the probability of throwing an even number with an ordinary six faced die

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

    B)         \[\frac{3}{5}\]                  

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

    D)         \[\frac{1}{3}\]

    Correct Answer: C

    Solution :

    Total number of outcome soft throwing a die = 6 Number of outcomes that are even numbers i.e., 2, 4, 6 = 3 \[\therefore \]The required probability \[\text{=}\frac{\text{Number}\,\text{of}\,\text{favourable}\,\text{outcomes}}{\text{Total}\,\text{number}\,\text{ofpossible}\,\text{outcomes}}\] \[=\frac{3}{6}=\frac{1}{2}\]
