Answer : E) Not enough information is given to determine the probability.

Step-by-step explanation:

Le A denotes the event that households in the United States own dogs.

and B denotes the event that households in the United States own cats.

As per given, we have

P (A) = 36.5% = 0.365

P (B) = 30.4% = 0.304

To find the probability that the selected household will own a dog or a cat, we apply the following formula:

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

But P (A and B) is not given to us.

i ... e the probability that a house hold own both a cat and adg is not given to us.

Therefore, The correct option is (E) Not enough information is given to determine the probability.
