Suppose P and Q are equivalent sets and n(P)=17.
What is the maximum number of elements in P u Q? What is the minimum?
What is the maximum number of elements in P n Q? What is the minimum?
Any help is appreciated! Thanks!

Best ResponseYou've already chosen the best response.0I think maximum of n (P or Q) = 34 minimum is 0 (the case they are not overlap at all. I mean they are separated) the max of n(P and Q) = 17. the min =0.

Best ResponseYou've already chosen the best response.0Yes. For example if P = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17} and Q = {a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r} then n(PuQ) = 34. But if P = Q then n(PnQ) = 17
