At central online high school, 45/100 of the children have a dog, 30/100 of the children have a cat, and 18/100 of the children have both a dog and a cat. what is the probability that children who have a cat also have a dog?

The probability of children who have both a cat and a dog is 63/100 or 63%

Explanation:

45/100 or 45% of the children already have a cat so you would add that to the amount of kids who already have a cat and a dog (18%)...Therefore 63% of students have a cat already may also have a dog.
