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.
| Litter | Number of Spotted Puppies | Total Number of Puppies |
|--------|--------------------------|--------------------------|
| 1 | 4 | 8 |
| 2 | 6 | 10 |
| 3 | 5 | 9 |
Total number of spotted puppies = 4 + 6 + 5 = 15
Total number of puppies = 8 + 10 + 9 = 27
Probability of a puppy having spots = Total number of spotted puppies / Total number of puppies
Probability = 15 / 27 = 5 / 9
Therefore, the probability of a puppy having spots in the next litter is 5/9.
