Question

honey goes to school either by a car driven by her driver or uses her bicycle. probability that she uses the car is 3/7. if you are her friend , what mode of transport you would suggest to her. and why would you ask her to option that mode of transport.

Answer 1

$$\begin{gathered} \mathrm{The}\mathrm{probability}\mathrm{that}\mathrm{he}\mathrm{will}\mathrm{use}\mathrm{car}=\frac{3}{7} \\ \mathrm{So}\mathrm{probability}\mathrm{of}\mathrm{using}\mathrm{bicycle}=1-\frac{3}{7}=\frac{4}{7} \\ \mathrm{SO}\mathrm{probability}\mathrm{of}\mathrm{using}\mathrm{bicycle}\mathrm{is}\mathrm{more}\mathrm{than}\mathrm{that}\mathrm{of}\mathrm{car}\mathrm{so} \\ \mathrm{he}\mathrm{should}\mathrm{use}\mathrm{bicycle}. \end{gathered}$$
