Final answer:
If a home has a garage, the probability it also has a pool is 75%, according to the real estate ads information provided.
Step-by-step explanation:
To calculate the probability that a home for sale has a pool given that it has a garage, we must look at the conditional probability based on the information provided.
The statement in the real estate ads suggests that 75% of homes have both a garage and a pool. If we know that a home has a garage, the probability that it also has a pool is already given in the question itself: 75%.
This is because the presence of a garage is a given condition, and out of those homes, 75% also have a swimming pool.
