The number who have one or more animals is 14+7-5 = 16
so, 10 of 26 have no animal
so, 10 + (14-5) have no dog
so, 10 of 26 have no animal
so, 10 + (14-5) have no dog
Wrong, Skylar! Please don't answer any more questions!
The ones who have only cats do not have a dog.
14/26 = 7/13
The ones who have only cats do not have a dog.
14/26 = 7/13
Oobleck, don't you mean:
The number who have one or more animals is 14+7+5 = 26?
5 have a cat and a dog.
The number who have one or more animals is 14+7+5 = 26?

To find the probability that a student chosen randomly doesn't have a dog, we need to find the number of students who don't have a dog and divide it by the total number of students in the class.
Out of the 26 students, only 7 have a dog, so 19 students do not have a dog. Therefore, the probability that a student chosen randomly from the class does not have a dog is:
19/26
