Newcastle weren't lucky.
It's not down to luck goal line technology isn't in place.
The only things you can account for are refereeing decisions that went against Newcastle. The free kick that led to the 2nd disallowed goal was never a free kick in a million years. The decision to not play advantage for Ben Arfa when through on goal in a 3v1 attack was borderline criminal.
As bad as the linesman was for Everton the referee was every bit as bad for Newcastle. Newcastle were the better team in the 2nd half and Everton paid for missed chances, a draw was fair.
Of course it's lucky when the ball crosses the line and the officials aren't sure, saving you a goal. It's also lucky when your opponents score a goal that's incorrectly ruled out for offside. You're confusing luck with the officials making howlers.
Whether the decisions balanced themselves out or not, I don't know as I didn't see the game. If I was an Everton I would be more concerned with how they gifted Newcastle a goal right after retaking the lead rather than whether they were unlucky.
