Question

A bag contains 5 red marbles, 6 blue marbles, and 9 green marbles. About how many red marbles would you expect to draw if you did 100 draws?

Answer 1

Answer: 25

Step-by-step explanation: Add all of the marbles, which is 20 in total, it is 5/20, so the ratio is 5:20

5:20 is 10:40, 15:60, 20:80, and 25:100

The answer is correct because 5:20 is 25% and 25/100 is also 25%
