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?
1 answer:
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%
