For problems 1–5, use the Venn diagram, which represents the relationship between favorite sport (soccer or baseball) and pet ownership (own a pet or doesn’t own a pet).

1.

How many people said soccer is their favorite sport?

2.

How many pet owners are in the data?

3.

How many of those who don’t own pets chose baseball?

4.

What is the probability that a person would say soccer is their favorite sport?

$P (soccer) =$

5.

What is the probability that a pet owner would say soccer is their favorite sport? (“Out of all pet owners, % say soccer is their favorite sport.”)

$P (soccer | pet owner) =$

Explain how your response fits with the given model.

6.

How many people said math is their favorite subject?

7.

How many tenth graders are in the data?

8.

How many ninth graders chose science?

9.

What is the probability that a person would say science is their favorite subject?

$P (s) =$

10.

What is the probability that a tenth grader would say science is their favorite subject? (“If you are a tenth grader, then the probability of science being your favorite subject is %.”)

$P (science | tenth) =$

Explain how your response fits with the given model.
