Hi, So I'm studying discrete math and I have some questions: 1.For this question,in the answer we use inexclusive or,why is it wrong to use exclusive or? p: You can use wireless network in the Airport q: You pay the daily fees r: you are subscriber ... 2.Help me figure out this question :translate Actors are not the only people who own an Iphone using propositional logic.. Thanks in advance.

Let G be a connected 3 - regular graph. Each edge of G lies on some cycle. Let S⊆V and C1,C2,…,Cm,m=Codd(G−S), be the odd component of G−S. Let eG(Ci,S) denote the number of edges with one- end in Ci and the other in S. Then ∑(i=1 to m) eG(Ci−S) is (1) ≤m (2) ≥5m (3) ≥3m
