There are 10 marbles in a bag. Tyrell draws one marble out at a time without looking and replaces it in the bag. Tyrell did this 100 times. Tyrell drew red marbles 9 times, green marbles 53 times, and blue marbles 38 times. Based on this Tyrell's experiment, predict how many of each color marble is in the bag. A. 1 red,1 green, and 4 blue B. 3 red, 3 green, and 4 blue C. 1 red, 5 green, and 4 blue D. 3 red, 4 green, and 3 blue

The best choice is 'C'. If it's 1, 5, and 4, then ideally, in 100 draws, you would expect 10, 50, and 40 ... pretty close to Tyrell's actual experimental results.
