Amanda used a standard deck of 52 cards and selected a card at random. She
recorded the suit of the card she picked, and then replaced the card. The
results are in the table below.
Diamonds
Hearts
Clubs
1. Based on her results, what is the experimental probability of selecting a heart?
2. What is the theoretical probability of selecting a heart?
3. Based on her results, what is the experimental probability of selecting a diamond or a
4. What is the theoretical probability of selecting a diamond or a spade?
5. Compare these results, and describe your findings.

P (hazel)= ______
b. Based on the survey, what is the experimental probability that a student in Dale’s
class has blue or green eyes?
c. Based on the survey, what is the experimental probability that a student in Dale’s
class does not have green or hazel eyes?
d. If the distribution of eye color in Dale’s grade is similar to the distribution in his
