In this pet show, there are exactly 18 animals. We obtain this by simply adding the numbers. Out of this number, there are 3 birds. The probability that a bird will win the show is calculated by dividing the number of birds by the total number of animals. This gives us the answer of 3/18 or equal to 1/6.
