Question

Victoria 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
18
Green
20
Yellow
12


Heads Tails
20 30

Using Victoria's simulation, what is the probability of pulling a blue marble and the coin landing tails up? (5 points)


48 over 50

38 over 50

540 over 2500

360 over 2500

Answer 1

The probability of pulling a blue marble and the coin landing tails up is calculated by multiplying the probability of pulling a blue marble (18 out of 50) by the probability of getting tails on the coin (30 out of 50).

So the probability is:
(18/50) * (30/50) = 540/2500

Therefore, the probability of pulling a blue marble and the coin landing tails up is 540 over 2500.
