In a bag of balls, 3 are yellow, 4 are blue, 6 are green, and 2 are red. Kay picks 30 balls from the bag, replacing the ball into the bag each time. How
many times would you expect a green ball to be picked?

12 marbles

Step-by-step explanation:

First, add the marbles together.

3 + 4 + 6 + 2 = 15

Then, put the 6 in the numerator.

6/15

Next, multiply by 2 to make the denominator 30.

12/30

Kay should expect 12 out of her 30 marbles to be green

Have a wonderful day! :)
