Dona used a probability simulator to pull 3 colored marbles from a bag and flip a coin 50 times. The results are shown in the tables below:

Color of Marble Number of Times Rolled
Blue 22
Green 16
Yellow 12

Heads Tails
22 28

Using Dona's simulation, what is the probability of pulling a blue marble and the coin landing tails up?
512 over 2500
616 over 2500
50 over 50
68 over 50

616/2500

Step-by-step explanation: You first have to find the number of times a Blue marbles was chosen: 22

Then find the total number of marbles that were chosen. Make a fraction out of it: 22/50

You then see how many times tails was flipped: 28

Do the same thing again: 28/50

Then multiply the two fractions together:

22/50 * 28/50 = 616/2500
