Suppose that 20% of people have a dog, 29% of people have a cat, and 13% own both. What is the probability that someone owns a dog or a cat? |
P(Dog) = 0.2
P(Cat) = 0.29
P(Dog and Cat) = 0.13
Probability that someone owns a dog or a cat = P(Dog or Cat) = P(Dog) + P(Cat) - P(Dog and Cat)
= 0.2 + 0.29 - 0.13
= 0.36
