Probability Simulations
For Exercises 1–3, place 5 red, 4 yellow, and 7 green marbles in a box. Randomly
draw two marbles from the box, record each color, and then return the marbles to
the box. Repeat this procedure 50 times.
1. Based on your results, what is the experimental probability of selecting two yellow
marbles?
2. Based on your results, what is the experimental probability of selecting a green marble
and a yellow marble?
3. Compare your results to the theoretical probabilities.
4. Color blindness occurs in 4% of the male population. What could you use to simulate this
situation?
SCHOOL CURRICULUM For Exercises 5–8, use the following information.
Laurel Woods High randomly selected students
for a survey to determine the most important
school issues among the student body. The
school wants to develop a curriculum that
addresses these issues. The survey results are
shown in the table.
5. Find the experimental probability
distribution of the importance of each issue.
School Issues
6. Based on the survey, what is the experimental probability that a student chosen at
random thinks the most important issue is grades or school standards?
7. The enrollment in the 9th and 10th grades at Laurel Woods High is 168. If their
opinions are reflective of those of the school as a whole, how many of them would you
expect to have chosen popularity as the most important issue?
8. Suppose the school develops a curriculum incorporating the top three issues. What is the
probability that a student selected at random will think the curriculum addresses the
most important issue at school?
