@Staratscience
OpenStudy (staratscience):
Im here hold on
OpenStudy (lynx):
Oh haha
OpenStudy (staratscience):
This is how to answer the question:
If 3∉B it follows that 3∈B'; the complement is everything *not* in B. Our first statement is true.
Since 3∈A it follows that 3∈A∪B, since A⊆A∪B and therefore everything in A is also in A∪B. Statement 2 is also true.
Now, since A and B do not have 3 in common, it follows that 3∉A∩B. Hence statement 3 is not true.
