Answer:
The probability of choosing a bay horse can be calculated by dividing the number of bay horses by the total number of horses:
Probability of choosing a bay horse = number of bay horses / total number of horses
In this case, we know that there are 5 bay horses and a total of 18 horses:
Probability of choosing a bay horse = 5 / 18
Therefore, the probability of choosing a bay horse is 5/18.
