Question

Real estate suggests that 90% of homes for sale have garages (let it be an event A), 15% have swimming pools (let it be an event B), and 10% have both features: a garage and a pool. a) What is the probability that a home selected at random has at least one feature (either a garage, or a pool, or both features)?​

Answer 1

The probability that a home selected at random has at least one feature (either a garage, a pool, or both features) is 0.95.

What is probability?

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have:

Event A: 90% of homes for sale have garages

Event B: 15% have swimming pools

Event(A∩B): 10% have both features.

P(A or B) = P(A) + P(B) + P(A∩B)

= 0.90+0.15 - 0.10

= 0.95

Thus, the probability that a home selected at random has at least one feature (either a garage, a pool, or both features) is 0.95.
