Probability Simulations

Skill Practice!

For Exercises 1–3, use a standard deck of 52 cards. Select a card at random, record the suit of the card (heart,
diamond, club, or spade), and then replace the card. Repeat this procedure 26 times.
1. Based on your results, what is the experimental probability of selecting a heart?

2. Based on your results, what is the experimental probability of selecting a diamond or a spade? .

3. Compare your results to the theoretical probabilities.

4. There are 3 siblings in the Bencievenga family. What could you use to simulate the genders of the 3
siblings?

5. A random survey of 23 students revealed that 2 students walk to school, 12 ride the bus, drive a car,
and 3 ride with a parent or other adult. What could you use for a simulation to determine the
probability that a student selected at random uses any one type of transportation?

BIOLOGY For Exercises 6–9, use the following information.
Eye color Blue Brown Green Hazel
Stephen conducted a survey of the students in his classes to
observe the distribution of eye color. Number 12 58 2 8
The table shows the results of his survey

6. Find the experimental probability distribution for each eye color.

7. Based on the survey, what is the experimental probability that a
student in Stephen’s classes has blue or green eyes?

8. Based on the survey, what is the experimental probability that a student
in Stephen’s classes does not have green or hazel eyes?

9. If the distribution of eye color in Stephen’s grade is similar to the distribution in his
classes, about how many of the 360 students in his grade would be expected to have
brown eyes?
