How do you calculate the odds of hitting?
To calculate that, simply multiply the chance to hit by itself. Again, a natural 1 always hits and a natural 20 always misses. If you need a natural 20 to hit, your chance to hit is 1400=0.0025 (0.25%). This is the minimum chance to hit with disadvantage.
How is DND hit calculated?
When attacking with a weapon, your bonus to hit is equal to your proficiency modifier plus your ability modifier (so at level 1, your proficiency modifier is +2, you said your strength is +3, so the total bonus is +5 – what D&Dbeyond is showing you). Your bonus to damage is just your strength bonus, so it’s +3.

How good is advantage5e?
With advantage, you’ll get it 51% of the time – about the same as you would get an 11 or better on a single d20. So advantage in this case is worth about a +4. Disadvantage, similarly, is about a -4: You only succeed 9% of the time with disadvantage, which is about the same as a single d20 with a target of 19.
Do you add proficiency to damage?
You never add your Proficiency Bonus to your damage rolls, even if you have proficiency in the weapon or spell.

What’s the chance of success on a d20?
With a straight d20, you have a 50% chance of success. With advantage, this goes up to 75%. That’s the equivalent of a +5 bonus to the roll, since you would also have a 75% chance of success if you only needed a 6 or better on a single d20. Pretty impressive!
How are hit dice calculated in dungeons and Dragons?
In the original D&D rulebook Men & Magic (1974), p.190, a chart was provided to determine the roll needed to hit, based on the attacker’s level and the target’s armor class. A separate chart on page 20 determined monster to-hit values based on their “dice”, i.e. hit dice, a concept roughly equivalent to character level.

How is THAC0 calculated in dungeons and Dragons?
Each player character and monster has a statistic known as THAC0, which is calculated based on their level or hit dice. Against an opponent with an armor class of zero, you must roll equal to or above your own THAC0 on a twenty-sided die in order to score a hit. In practice, most opponents do not have an armor class of zero.
