Answer 1

Dear student
$$\begin{gathered} \mathrm{If}\mathrm{the}\mathrm{card}\mathrm{has}\mathrm{the}\mathrm{order}\mathrm{of}\mathrm{numbers}\mathrm{as}:1,2,3,4,5,6,7,8,9 \\ \mathrm{Total}\mathrm{numbers}=9 \\ \mathrm{Composite}\mathrm{numbers}\mathrm{till}9\left(\mathrm{Favouable}\mathrm{outcomes}\right)=4,6,8,9 \\ \mathrm{Probability}=\frac{\mathrm{Favouable}\mathrm{outcomes}}{\mathrm{Total}\mathrm{outcomes}} \\ \mathrm{Probability}\left(\mathrm{Composite}\mathrm{numbers}\mathrm{till}9\right)=\frac{4}{9} \end{gathered}$$
