To find the theoretical probability of the family having three dogs or three cats, we need to consider all the possible outcomes.
There are 2 possibilities for each pet: dog or cat.
So, the total number of possible outcomes for three pets is 2 * 2 * 2 = 8.
For three dogs: There is only 1 way for the family to have three dogs.
For three cats: There is also only 1 way for the family to have three cats.
Therefore, the total number of favorable outcomes is 1 + 1 = 2.
The theoretical probability of the family having three dogs or three cats is 2 favorable outcomes / 8 total possible outcomes = 1/4 = 25%.
