57.7981651376147 chance of survival. I don't see why that came out so low, I mean have lot swords, guns,knives, and many of blunt objects, and my brother and I have the ultamite zombie survival plan. Very extensive plan essential we grab our weapons, got to my cousins house get his guns, than go north to a gun store we know, than continue north to an island cottage we have. FYI the cottage has a loft that you need to climb a ladder to get into, and multiple shotguns in a safe (double barrel, 12 gage, 20 gage, 22. pistol and rifle)
PS- My family is full of redneck hunters, so we should be fine for at least 2 months untill the ammo runs out.
