Are You a Gambler? To Roll or Not to Roll Your Hit Points

In fifth edition you have the option of either rolling for your hit points when you level or taking the average. 

I always advise players to take the average, but many times they don't, and they often regret rolling. 

If you're going to gamble, it's always good to know the odds. The larger your hit die, the better your chance of getting a decent roll. I'll share the numbers with you, and you can make your own decision. 

With every hit die, your chance of rolling less than the average score is 50%.

With a d6 hit die, if you take the average you get 4 hit points. If you roll, you only have a 33% chance to roll better than a 4.

With a d8 hit die, if you take the average you get 5 hit points. If you roll, you only have a 38% chance of rolling higher than 5.

With a d10 hit die, if you take the average you get 6 hit points. If you roll, you only have a 40% chance of rolling higher than a 6.

With a d12 hit die, if you take the average you get 7 hit points. If you roll, you only have a 42% chance of rolling higher than 7. 

Just for fun, if you could have a d20 hit die, the average would be 11 hit points. If you rolled, you'd only have a 45% chance of rolling higher than 11.
