Question

Cathy 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
12
Green
18
Yellow
20


Heads Tails
30
20


Using Cathy's simulation, what is the probability of pulling a blue marble and the coin landing tails up?240 over 2500

220 over 2500

12 over 50

32 over 50

Answer 1

240 over 2500

220 over 2500

12 over 50

32 over 50 pick one

Answer 2

The probability of pulling a blue marble is 12/50 and the probability of the coin landing tails up is 30/50.

Therefore, the probability of both events happening together is (12/50)*(30/50) = 240/2500 = 24/250 = 12/125.

So the correct answer is 12 over 125.

Answer 3

240 over 2500
