Question

Help plss;-;

Misha 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
20
-Green
18
-Yellow
12


Heads-28 Tails-22

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

A. 410 over 2500
B. 440 over 2500
C. 32 over 50
D. 42 over 50

Answer 1

Consider the two events separately

- what is the probability of pulling a blue? Calculate (number of blue marbles)/(total # of marbles)

- what is the probability of the coin landing tails up? Calculate (# of tails)(total # of coin flips)

To find the probability of both events happening, multiply the two probabilities together
