Nolan runs a stable that boards 4 brown horses, 9 black horses, 3 brown and white horses, and 2 black and white horses. What is the experimental probability that the next horse that comes to board is brown?

I believe that it is 22.2%. There are 18 horses and 4 of them are brown, meaning that there is a 4/18 chance that the horse that comes to the board is brown. When you divide 4 from 18 you get 22.2, which would make the probability 22.2%.

10.4 is the answer for you
