Discrete Math Structure --> Set Operation. I asked in a previous question what is the "c" in c(A), and @tamtoan answered that it is for count. I was able to figure out the first question, but can't get the correct answer for the second question. The second question is: If c(A Union B) = 17, c(A Intersect B) = 3, and c(A) = c(B), then c(A) = ____? So, intersection is 3. Union is 17, which means, c(A) and c(B) should have 7 each right? I entered 7, but the result shows it up as incorrect. Did I make a silly mistake somewhere? >_< Thank you.
