Answer 1

Explanation:

Given data:

Cars Vans Others

60 21 3

Find the relative frequency;

It is the number of times an event occurs.

Here the time frame is within a day;

Relative frequency =
`(number of cars + number of vans + others)/(number of days)`

Relative frequency = 60 + 21 + 3 = 84vehicles per day

Number of vans in a week;

Number vans in a week = 21van per day x 7 days = 147vans
