In a class of 26 students, 14 have a cat and 7 have a dog. There are 5 students who have a cat and a dog. What is the probability that a
student chosen randomly from the class does not have a dog?

9/26

Step-by-step explanation:

Im sorry, but probablity is quite hard to explain, but I'll try my best. So what you know is that there are a total of 26 students right? Out of these 25, 14 have at least a cat, and 7 have at least a dog. But 5 of them have a cat and a dog. This means that 14-5, and 7-5, are for only a cat and only a dog respectively. So, people with only a cat don't have a dog, meaning that 14-5, which is 9 people only have a cat. Therefore, out of the 25 people, only 9 don't have a dog, making the probablitly 9/25.
