3 is an element of B complement. 3 is an element of A∪B. 3 is an element of A∩B.

OpenStudy (lynx):

If 3\(\notin\)A and 3B, then which of the following statements is not true?

OpenStudy (lynx):

@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.

OpenStudy (lynx):

So the answer would be C?

OpenStudy (staratscience):

Yes
