apoorvk · Answer

union of any two sets contains all the combined elements of those two sets.
intersection contains only the common elements of the two sets.

now what do you think the answer should be??

anonymous · Answer

intersection G?

apoorvk · Answer

yeah. and what about union? (dont forget to write it in set notations and use small 'g' as mentioned in question)

anonymous · Answer

I am still not understanding the union. my guess is c,d,f,g,i ?

anonymous · Answer

what you wrote last is the union of M and B, the collection of everything from M and B.

anonymous · Answer

now the intersection is just the collection of elements they have in common....

anonymous · Answer

Thank you so much!  What kind of math is this?

anonymous · Answer

this can be a combination... it is used in all math from algebra all the way up...

apoorvk · Answer

this is set-theory!!
