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? (1 point)

512 over 2500

616 over 2500

50 over 50

68 over 50

1 answer

To find the probability of pulling a blue marble and the coin landing tails up, we need to find the number of times both events occurred and divide it by the total number of trials.

Number of times pulling a blue marble and coin landing tails up = 22

Total number of trials = 2500 (50 coin flips x 50 trials)

Probability = Number of times pulling a blue marble and coin landing tails up / Total number of trials
Probability = 22 / 2500

Therefore, the probability of pulling a blue marble and the coin landing tails up is 22 over 2500.
