    A child has a block in the shape of a cube with one letter written on each face as shown. \[\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\] If the cube is thrown once, what is the probability of getting A?

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

    B)        \[\frac{2}{8}\]                   

    C)         \[\frac{2}{5}\]                                  

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

    Correct Answer: A

    Solution :

    Random drawing of blocks ensures equally likely outcomes. The total number of blocks representing A = 2 Total number of possible outcomes \[=6P(A)=\] \[\frac{\text{Number}\,\text{of}\,\text{favourable}\,\text{outcomes}}{\text{Total}\,\text{number}\,\text{of}\,\text{possible}\,\text{outcomes}}\] \[\text{=}\frac{2}{6}=\frac{1}{3}\]
