On a busy road in

Answer :

According to the Data of 60 cars we need to find the probability of an event for a car passing after the interval.

Here, we’ll be finding out empirical probability.


(i) Only two persons sitting in it


No. of cars with 2 persons in the interval = 16


Total number of cars = 60



(ii) Less than 3 persons in it


This is satisfied when the number of persons is 1 and 2 in a car.


No. of cars with 1 persons in the interval = 22


No. of cars with 2 persons in the interval = 16


Total number of cars = 60




(iii) More than 2 persons in it


This is satisfied when the number of persons is 3, 4 and 5


No. of cars with 3 persons in the interval = 12


No. of cars with 4 persons in the interval = 6


No. of cars with 5 persons in the interval = 4


Total number of cars = 60




(iv) at least 4 persons in it


This is satisfied when the number of persons is 3, 4 and 5


No. of cars with 4 persons in the interval = 6


No. of cars with 5 persons in the interval = 4


Total number of cars = 60
