i have tried everything At Central Online High School, 45100 of the students have a dog, 30100 of the students have a cat, and 18100 of the students have both a dog and a cat. What is the probability that students who have a cat also have a dog?

Work Shown:

Let's say this school has 100 people total. We know that 30 of the people have a cat since 30/100 is the fractional portion of cat owners. Similarly, 18 have both a cat and a dog.

The probability of selecting someone who has both pets, given we know they are a cat owner, is 18/30 = 3/5

To reduce the fraction, divide both parts by the GCF 6.

Note: we don't use 45/100 because we know that whoever selected wasn't solely a dog owner.
