Question: Answer and explain the answer below. How many students are wearing a hat, but not a sweatshirt?

Answer: It is unknown because three of the students didn't survey so It could be no more than 3 because it says 7 students are wearing a sweatshirt, 3 students are wearing a hat and a sweatshirt, and 5 students are not wearing either a sweatshirt or a hat.

Hope it helps.
