If A ⊂ B, then A ∩ B = B A ∪ B = B A ∩ B = ∅

so seeing the venn diagram you can answer this question where A is a subset of B
Ok, A is a subset of B. The numbers in B may not all be in A. This will probably be easier with an example. Lets say that the numbers {1, 3, 4, 7, 9, 11} are in set B. The numbers {3, 4, 7} are in set A.
As you can see, all of the numbers in set A are also in set B.
So it would be the first answer then?
A intersection B wouldn't be B, it would be A since the numbers in both sets are {3, 4, 7}.
So the second one? Lol
yep! :)
Thanks so much again!:):):)
No problemo! :D
You are making me dig back like 2 years for this stuff haha :)
Lol I just started Algebra 2. I've taken Algebra, but that was well over a year ago so it's difficult to remember! I'm sorry
Its fine :)
