An Australian Shepherd breeder has had three litters of puppies from the same set of parents. The following table shows the results from the three litters. In the next litter, what is the probability of a puppy having spots? Enter a fraction or round your answer to 4
decimal places, if necessary.
Number of Puppies
Black and White Red and White Black with Spots Red with Spots
8
5
6
4
Total number of puppies = 8 + 5 + 6 + 4 = 23
Number of puppies with spots = 6 + 4 = 10
Probability of a puppy having spots = 10/23
Therefore, the probability of a puppy having spots in the next litter is approximately 0.4348.
