Hello all, I'm trying to find out the probabilities of certain outcomes in this X-wing Miniatures game I play, so I'm hoping someone who's good at calculating this sort of thing can figure out the following for me:
The parameters: There are 2 types of dice, attack and defense. Both are D8's, with the following sides: Attack: 3 hit symbols, 1 crit symbol, 2 focus symbols, 2 blank symbols Defense: 3 evade symbols, 2 focus symbols, 3 blank symbols Hits and crits are 1 damage each, evade symbols cancel 1 hit each. Any hits/crits left uncanceled are 1 damage per dice. Blanks do nothing. Focuses are variable (explained below). For the purposes of these scenarios, crits are basically just hits. Scenario 1: If I roll 3 attack dice, and my opponent rolls 2 defense dice, what are the odds of dealing at least 1 damage? Please count "focus" symbols as "blank" symbols. Scenario 2: The above, but 4 attack dice vs 3 defense dice. Scenario 3: 3 attack dice vs 2 defense dice. Please count "focus" symbols as "hits" for attack and "evades" for defense. Scenario 4: The above, but 4 attack dice vs 3 defense dice. Or if you don't want to actually do the math, if you can tell me what the formulas would be here I can also follow those instructions and calculate it myself.

let me see if I can work through this for scenario 1 at least
0 DEF: 25/64 (5/8 x 5/8) 1 DEF: 30/64 (3/8 x 5/8) + (5/8 x 3/8) 2 DEF: 9/64 (3/8 x 3/8) 0 ATT: 1/8 (1/2 x 1/2 x 1/2) 1 ATT: 3/8 (Hit Miss Miss, Miss Hit Miss, and Miss Miss Hit, all at 1/8 each) 2 ATT: 3/8 (HHM, HMH, MHH, 1/8 each) 3 ATT: 1/8 (1/2 x 1/2 x 1/2) 25/64 x 7/8 = 175/512 is the % of getting and beating 0 def 30/64 x 4/8 = 120/512 for 1 def 9/64 x 1/8 = 9/512 for 2 def Add that up and it's 304/512 if I'm not confused, or 59.375% of at least 1 hit --- I have the power of God AND anime on my side The problem is the racism against cute Pokemon. - Luster Soldier ...

think you've missed critical hits on offense, tom

I have 59.38%, 61.67%, 83.94%, and 87.17%. Excel is very helpful for this by the way.

I counted them as hits (right?)

my bad - assumed they were worth 2 damage instead of 1

Are crits canceled by evades?

Awesome you guys, thank you.
Assuming Sceptile is on the money with the other 3 scenarios, I'm surprised it's that much of a jump when adding in the focus symbols. I know it bumps up a single attack dice's chance to hit to 75%, while a single defense dice's chance to evade only goes to 62.5%, but a 20%+ bump is significant. Also glad to know that my hunch about simply adding a dice to both sides has minimal effect (which I guess is common sense but hey, if I were sure about this stuff I'd have done it myself right?) Thank you guys so much. Edit: Ah, I see there is some discrepancy on tera's side. I will wait for further data, but still thanks everyone for all the effort. --- I'm a greener egg than the eggs from dr. seuss ... Copied to Clipboard!

Are crits canceled by evades? It's not really relevant for the purpose of this calculation, but in the game you have to cancel all hits before you can cancel crits. IE if you roll 2 hits and a crit, and your opponent rolls 2 evades, they have to cancel the hits and take the crit. But if you only roll 1 hit and a crit, and they roll 2 evades, then yes the crit gets canceled. --- I'm a greener egg than the eggs from dr. seuss ... Copied to Clipboard!

Awesome you guys, thank you. Wait, you wanted to count the focuses for defense too? I didn't do that. Easy to change if so. Looking at it again, I see where I was misreading. Now it's 69.87% and 70.45% for the second set. --- Just killing time until the world ends. ... Copied to Clipboard!

btw, intuitively, this should make sense to you (that increasing the attacking dice's probability improves their chances of succeeding overall)
if you take this to the logical limit and say that your X+1 offensive dice have 4 HIT and 4 FOCUS and your X defensive dice have 3 EVADE and 4 FOCUS, you should expect to get X+1 hits every time - which of course is impossible to evade completely, so you'd succeed at 100% --- yet all sailors of all sorts are more or less capricious and unreliable - they live in the varying outer weather, and they inhale its fickleness ...
