Write a probability model for this experiment, and use the probability model to predict how many times Brianna would pick a green marble if she chose a marble 50 times. Give the probabilities as simplified fractions.



Drawing a red marble



Drawing a white marble



Drawing a black marble



Drawing a green marble



Brianna would draw
green marbles in 50 tries.

Ryan asks 80 people to chose a marble, note the color, and replace the marble in Brianna's bag. The results of the random marble selections in this experiment are: 34 red, 18 white, 9 black, and 19 green marbles. How does the theoretical probability compare with the experimental probability of drawing a white marble?





The theoretical probability of drawing a white marble is
%.



The experimental probability of drawing a white marble is
%.



The theoretical probability is
than the experimental probability.

Question 3
- Drawing a red marble: 6/20 = 3/10
- Drawing a white marble: 7/20
- Drawing a black marble: 3/20
- Drawing a green marble: 4/20 = 1/5
- Brianna would draw 10 green marbles in 50 tries.

Question 4
- Theoretical probability of white: 7/20 = 35%.
- Experimental probability of white: 18/80 = 9/40 = 22.5%.
- The theoretical probability is greater than the experimental probability.
