Answer 1

Dear student
$$\begin{gathered} \mathrm{Integers}\mathrm{from}1\mathrm{to}100\mathrm{which}\mathrm{are}\mathrm{divisible}\mathrm{by}8: \\ 8,16,24,32,40,48,56,64,72,80,88,96 \\ \mathrm{So},\mathrm{P}\left(\mathrm{Integers}\mathrm{from}1\mathrm{to}100\mathrm{which}\mathrm{are}\mathrm{divisible}\mathrm{by}8\right)=\frac{\mathrm{Favourable}\mathrm{outcomes}}{\mathrm{Total}\mathrm{outcomes}}=\frac{12}{100}=\frac{3}{25} \end{gathered}$$
