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?
540/2500
48/50
38/50
360/2500

Answer 1

Answer:

C. 540/2500

Step-by-step explanation:

18 times 30=540

50 times 50= 2500

Answer 2

Answer: $\dfrac{540}{2500}$

Step-by-step explanation:

Formula:

$\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}$

Using Victoria's simulation :

Total number of outcomes = Total number of times marbles rolled x Total number of times coin flipped

= 50 x 50 =2500

Favorable outcomes = Total number of times pulling a blue marble and the coin landing tails up

= Number of times blue marble rolled x Number of times coin flipped to tail

= 18 x 30=540

Now, the  the probability of pulling a blue marble and the coin landing tails up will be :-

$=\dfrac{540}{2500}$
