In the United States, 30% of people own a cat and 3% of people own a bird. What is the probability of someone owning both a cat and a bird?

Answer: 9/100

Step-by-step explanation:

Probability of people own a cat:

P (cat) = 30/100=0.3

Probability of people own a bird:

P (bird) = 3/100=0.03

Probability of both own a cat and a bird

P (cat and bird) = (30/100) * (3/100)

=90/1000=9/100=9%
