Question 1 of 10
1. How to find out how many white cars are in Moscow?
Use the extrapolation method: count the number of white cars that drove along the Moscow Ring Road in half an hour. In a day 48 times for half an hour. Multiply - you get the approximate number of cars.
Find data on the number of registered cars in Moscow. I will assume that white is the most popular color. I will assume that it accounts for 20%. I'll do the count.
