Marie Caldwell · Answer 1

5/9

Step-by-step explanation:

35 households have only cats, 24 have only dogs, 19 have both cats and dogs, and 28 have neither.

The total number of households without dogs is 35 + 28 = 63.

The number of these households that have cats is 35.

So the probability is 35/63 = 5/9.
