The probability of owing a dog or a cat by an American household is 0.669.

What is probability?

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lie in the close interval of 0 and 1 [0,1].

Given that,

The percent of households owning dogs is 36.5%.

The percent of households owning cats is 30.4%.

Suppose, A be the event of owning dogs and B of owning cats.

Then, as per the question P(A) and P(B) is given as,

P(A) = 36.5%

       = 36.5/100

And, P(B) = 30.4%    

                = 30.4/100

Now, P(A or B) is given as,

P(A or B) = P(A) + P(B)

               = 36.5/100 + 30.4/100

                = 66.9/100

                = 0.669

Hence, the probability that the selected household will own a dog or a cat is 0.669.
