ddcamp · Answer

numbers, letters, same idea. What letters are in both A and C?

anonymous · Answer

I thought I did put the letters in first post...?

anonymous · Answer

The problem looks like this: (A n C)'...that n is the intersect symbol.

ddcamp · Answer

What letters are in both of these lists, that will be the intersect of A and C:
{a,c,d,f,g,i}
{a,b,f,i,j}

The letters in U that are not in the new list would be the complement of (A n C)
