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.
red frequency 2
blue frequency 4
yellow frequency 2
black frequency 6
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: 2 yellow marbles were pulled out of 14 total pulls, so the experimental probability is 2/14 = 0.14.
Theoretical probability: There are 4 yellow marbles out of a total of 20 marbles, so the theoretical probability is 4/20 = 0.20.
