The weapon damage can go in between 2 numbers which implies that it will hit the enemy for a random number set in between those specifications. If a monster has for example 12 HP, it can pass away either in 2 hits or 3 hits. There is a possibility that the monster will obstruct the attack (or part of it) and you require to take that into factor to consider too. Constantly wish for the very best, however get ready for the worst! You never ever know precisely what the monster will do given that all of it depends upon RNG, so anticipate anything!
