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