Explanation:
If 13% of people own dogs, then the probability that a randomly selected person owns a dog is 0.13. Assuming that the ownership of dogs is independent between people, the probability that two randomly selected people both own a dog is equal to the product of their individual probabilities:
P(both own a dog) = P(1st person owns a dog) * P(2nd person owns a dog | 1st person owns a dog)
P(both own a dog) = 0.13 * 0.13
P(both own a dog) = 0.0169
Therefore, the probability that two people picked at random both own a dog is 0.0169 or approximately 1.69%.
