This is related to Dungeons and Dragons:
Your character has just been reduced to 0
Hit Points (HP)
(because of a fireball) and is now dying. They must now make several
Death Saving Throws
to determine their fate.
Death saving throws are rolled every turn until you get three successes or three failures.
To make a death saving throw, simply roll a d20. If the roll is 10 or higher, you succeed. Otherwise, you fail.
On your third success, you become stable. On your third failure, you die.
If you roll a 1, it counts as two failures.
If you roll a 20, you regain 1 hit point. In which case, you regain consciousness and can fight once more!
Calculate the probability that your character dies.
