Suppose another car passes by. Find the chance that it has
(i) exactly 5 occupants
(ii) more than 2 occupants (iii) less than 5 occupants.
Solution
otal number of cars = 29 + 26 + 23 + 17 + 5= 100
(i) Number of cars having exactly 5 occupants = 5
∴ Probability that it has exactly 5 occupants = 
(ii) Number of cars having more than 2 occupants = 23 + 17 + 5 = 45
∴ Probability that it has more than 2 occupants 
(iii) Number of cars having less than 5 occupants = 29 + 26 + 23 + 17 = 95
∴ Probability that it has less than 5 occupants
