Question

Each year, 70% of Grandma's rose entries won blue ribbons. If she entered 20 roses, how many blue ribbons can she expect to win?

Answer 1

To find your answer you have to divide 70 by 100 to get 0.7. You then multiply 20 by 0.7 to get a product of 14. That means 14 of the the roses would be expected to win
