Question

Recent estimates say that 66% of U.S. homes have a garage or carport, 10% have a swimming pool, and 8% have both. If a randomly selected home has a garage, what is the probability it has a pool

Answer 1

Answer:

0.12

Step-by-step explanation:

From the given info, we have: P(G) = 0.66, P(S) = 0.1,  P(G and S) = 0.08

where G = Garage, and S = swimming pool

In other words, find the conditional probability P(S|G).

Use conditional probability definition, P(S j G) = P(S and G)=P(G)

= 0.08 / 0.66 = 0.12
