There is a bag of 50 marbles. Andre takes out a marble, records its color, and puts it back in. In 4 trials, he gets a green marble 1 time. Jada takes out a marble, records its color, and puts it back in. In 12 trials, she gets a green marble 5 times. Noah takes out a marble, records its color, and puts it back in. In 9 trials, he gets a green marble 3 times. Estimate the probability of getting a green marble from this bag.

As an  guess I would say

 

Andre has success 9/36  of the time

Jeda has success 15/36 of the time

Noah has success 12/36 of the time

 

Averaging thse you get 1/3

 

So the probability of getting a green marble is approximately 1/3
