Math request

[N.I.B.]

Can someone do the math for the chance of a Tervigon with 3 powers to roll either Iron Arm or Endurance (and remember the reroll of same results) please?

I am getting 80%.

Without Re-rolls, you have a 70% chance of getting one of them (152 of 216).

Of those 64 failure, you will get a re-roll in 40 of the cases. (You would get more than this, these are just the failures that give a reroll)

On the one dice re-roll, you have a 50% of getting one of the result. In the case of two re-rolls, have a 70% of getting what one of the two. This gives you an chance of 52% to get one of your two expected results. This gives you 20.8 additional successes, for a total of 172.8 of 216.

So, one out of every 5 games, you won't get it. If I get time later, I'll check for the chance to get only 1.

Shouldn't it be about 1/2 chance.. You get to draw 3 cards out of 6 (circumvent the re-roll), so you get 50% chance to get iron arm specifically, and you get 50% for Endurance.

Now if you're happy with either one, you get about 75%?

Let's see, the first Roll has a 4/6 chance of not getting either. Assuming it fails, the second Roll now has a 3/5 chance of not getting either. Continued fail gives the third Roll a 2/4 chance of not getting either. Multiplying those together comes out with a 20% chance of not getting any of them, so yeah, 80% chance to get at least one of the two with three Rolls.

Sure...do it the easy way.

What can I say, I'm lazy. That's why I majored in Math in the first place

Nib doesn't like getting warp speed D:

Its not that Warp Speed sucks, its the fact the other two are so good before you get to combat, and are still relevant once you get there.
