i got b

Answer 2

Are you only allowed to pick one? can more than one be true?

Answer 3

OH WAIT... false.. nvr mind.

Answer 4

only one

Answer 5

Only one is false. But it isn't the 2nd one.

\[B \subseteq B\] means that B is either = to, or a subset of, B. That's always true, right? A set is always \(\subseteq \) of itself.

Answer 16

A is the one that is True.
Because A intersection B = {4,8,10} which is B itself!! :D
