Question

Red 13 Silver 34 Black 25 White 10 Blue 8

Estimate the number of white cars you would expect to see if 4000 cars passed by?

Answer 1

Answer: You will expect 444 white cars passed by.

Explanation:

The are 5 different colors so we need to find the probability of white cars.

There are 10 white cars But we need to find the total number of cars in all.

13+34+25+10+8 = 90

so the probability of a white car passing by is 25/90 = which reduces to 10/90

Now multiply 1/9 by 4000.

1/9 * 4000 = 444

Answer 2

444

Explanation:

13 + 34 + 25 + 10 + 8 = 90

10/90 * 4000 = 444
