Result= Q + NOT(P) ..

Result= NOT(P.NOT(Q))

Draw the truth table, P in columns and Q in lines (or the opposite), fill with "1" and "0" and it should be obvious.

1) Result=not(p) or (P and Q)
2) Distribute not(p): result=(not(p) or p) and (not(p) or q)
3) Use identities: result=1 and (not(p) or q)
4) Simplify: result= not(p) or q.
