Hello there i hope you are having a great day :) Your question: Suppose 21% of people own a dog. If you pick two people at random, then what is the probability that they both own a dog?
1) 21% own a dog so you would do 21/100 = 0.21 this would equal the first person now the second person you would do 21/100 = 0.21
2) now you would multiply it so 0.21 x 0.21 = 0.0441 the that would be your answer.
Hopefully that helps you ❤
