Question

Shyla 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 16
Green 20
Yellow 14

Heads Tails
18 32

Using Shyla's simulation, what is the probability of pulling a blue marble and the coin landing tails up? (1 point)


512 over 2500

624 over 2500

32 over 50

48 over 50

Answer 1

To find the probability of pulling a blue marble and the coin landing tails up, we need to first find the total number of trials in the simulation.

Total number of trials = number of blue marbles pulled (16) + number of green marbles pulled (20) + number of yellow marbles pulled (14) + number of times coin landed heads (18) + number of times coin landed tails (32) = 16 + 20 + 14 + 18 + 32 = 100

Now, to find the probability of pulling a blue marble and the coin landing tails up:

Probability = Number of times blue marble and tails occurred / Total number of trials
Probability = 16 / 100
Probability = 16/100
Probability = 0.16

So, the correct answer is:

16 over 100
