Question

Suppose U={0, 1, 2, 3, 4, 5, 6}, A={2, 4, 6}, and B={1, 2, 3}.

Answer 1

It's hard to tell what question 1 is but if the question says Is A a subset of U then it is true.

And number 5 will be counted right regardless of the answer you put because it says it was entered in error and you will receive credit for any answer.
