Sum of Product and Product of Sum
I have a doubt it may be stupid though. know that if ∑m (1,3,5,6) then its equivalent POS form is = πM (0,2,4,7) But my doubt is say i need to represent 7, in SOP i write ABC in POS i write (A'+B'+C') ∑m (1,3,5,6) = A'B'C + A'BC+AB' ... then why we say that SOP is complement of POS and why ∑m (1,3,5,6) != πM(1,3,5,6) ? as according to above they seems to be equal.

Which process will be ... mean the waiting queue will have the order P2, P3, P4, P1 or P2, P3, P1, P4 because there is race between P4 and P1.
