Suppose that 31% of people own dogs. If you pick two people at random, what is the probability that they both own a dog?

Answer 1

since the events are independent you can just multiply the individual probabilities together!

0.31 * 0.31 = 0.0961

meaning that the probability that two randomly selected people both own a dog is about 9.61%
