To find the experimental probability, we need to divide the number of times Luis pulled a yellow marble (4) by the total number of times he pulled a marble (14).
Experimental probability = 4/14 = 0.29
To find the theoretical probability, we need to divide the number of yellow marbles in the bag (4) by the total number of marbles in the bag (3 + 5 + 4 + 8 = 20).
Theoretical probability = 4/20 = 0.20
Therefore, the experimental probability of pulling a yellow marble is 0.29, and the theoretical probability is 0.20.

Question
Luis has 3 red marbles, 5 blue marbles, 4 yellow marbles, and 8 black marbles in a bag. He records the color marble he pulls from the bag and puts the marble back in the bag 14 times. The table below shows the frequency he pulled each color.
What are the experimental and theoretical probability of pulling a yellow marble out of the bag? Round your answer to the nearest hundredth.
Experimental probability
Theoretical probability
