Question 33098
(A∩C) is A intersection C... where the 2 sets intersect. In other words "AND". The way i always remember it is: ∩ looks line an "n" which appears in the word "and". Foolish? Who cares...works for me.


So, (A∩C) is elements in A and C --> (a,c,d,g)


(BUC) means UNION --> U for Union. Since ∩ is AND, then U must be OR.


So, elements in B OR C --> {a,b,c,d,f,g,h,j,k}
and i think you want (BUC)' meaning NOT? then it will be all the other elements, namely (e,i,l,m)
