Question

A shopping centre car park has spaces for 8 buses, 160 cars and 12 motorbikes. If all vehicles have an equal chance of leaving at any time, find, expressing your answer as a proper fraction in its simplest form

Answer 1

Total number of vehicles: $N=8+160+12=180.$

Probability of bus: $\frac{8}{180}=\frac{2}{45}.$

Probability of car: $\frac{160}{180}=\frac{8}{9}.$

Probability of motorbike: $\frac{12}{180}=\frac{1}{15}.$
