    The pie chart given below represents the percentage of people in various occupations. On the basis of data given in the Pie-chart. What is the possibility that a person selected randomly chooses agriculture as a occupation?

    A)  \[\frac{1}{8}\]                         

    B)  \[\frac{3}{8}\] 

    C)  \[\frac{5}{8}\]                         

    D)  \[\frac{7}{8}\]

    Correct Answer: B

    Solution :

    (b): Corresponding angle to agriculture \[={{135}^{{}^\circ }}=n(E)\] \[n\left( S \right)={{360}^{{}^\circ }}\] \[n\left( P \right)=\frac{{{135}^{{}^\circ }}}{{{360}^{{}^\circ }}}=\frac{3}{8}\]
