Question

11. A sample study of 420 people, it was found that 240 people were government employees. If a person is selected at random, find the probability that the person is not a government
employee.

Answer 1

Dear student
$$\begin{gathered} \mathrm{Probability}\mathrm{that}\mathrm{a}\mathrm{person}\mathrm{is}\mathrm{not}\mathrm{a}\mathrm{givernment}\mathrm{employee}=1-\mathrm{Probability}\mathrm{that}\mathrm{a}\mathrm{person}\mathrm{is}\mathrm{a}\mathrm{givernment}\mathrm{employee} \\ =1-\frac{240}{420} \\ =\frac{420-240}{420} \\ =\frac{180}{420} \\ =\frac{3}{7} \end{gathered}$$
