SOLUTION: Suppose 67% of people own dogs. If you pick two people at random, what is the probability that they both own a dog?
Give your answer as a decimal (to at least 3 places)
67% of the time the first person you pick will own a dog.
67% of those 67% of the time the second person you pick will own a dog.
Answer 67% of 67% of the time = (0.67)(0.67) = 0.4489
