Fran has a bag of 20 marbles the bag has some blue, yellow and green she draws one marble at random records the color and returns it to bag her data after 1200 trials is 845 blue 305 green and 50 yellow what it the probability that a random marble drawn is blue

Since we do not know the exact number of Marbles of each color we will use the data of the experiment to calculate the probability. The probability calculated based on the results of an experiment is termed as experimental probability.

So, we have the calculate the experimental probability that a randomly drawn marble is blue.

Total number of trials = 1200

Number of times blue showed up = 845

Therefore, the experimental probability of randomly drawing a blue marble = 845/1200 = 169/240 = 0.704 (Rounding to nearest thousandth)

Therefore, the probability that a random blue marble is drawn is 0.704 or 169/240
