Someone has probably already done this, but I thought that I would post it
anyway.

Here are the average rolls (taking the higher of the die rolls) for the FMA
dice combinations:

By Dice Types: Dice Average Roll
d4/d4   3.1250
d6/d4   3.9166
d6/d6   4.4722
d8/d4   4.8125
d8/d6   5.2292
d8/d8   5.8125
d10/d4  5.7500
d10/d6  6.0830
d10/d8  6.5500
d10/d10 7.1500
d12/d4  6.7083
d12/d6  6.9861
d12/d8  7.3750
d12/d10 7.8750
d12/d12 8.6861

By Average: Dice Average Roll
d4/d4   3.1250
d6/d4   3.9166
d6/d6   4.4722
d8/d4   4.8125
d8/d6   5.2292
d10/d4  5.7500
d8/d8   5.8125
d10/d6  6.0830
d10/d8  6.5500
d12/d4  6.7083
d12/d6  6.9861
d10/d10 7.1500
d12/d8  7.3750
d12/d10 7.8750
d12/d12 8.6861

Now this does not tell the whole story in a FMA opposed roll.
While a d10 only has an average roll of 5.5 and a d8/d8
combination has an average roll of 5.8125, there are 2 results
on a d10 that will beat any combination of d8/d8. Still, the
results are interesting.

Assuming I wrote the spreadsheet expressions correctly:

                                       Defender
4 6 8 10 12
4	37.50%	   25.00%     18.75%	 15.00%     12.50%
6	58.33%	   41.67%     31.25%	 25.00%     20.83%
8	68.75%	   56.25%     43.75%	 35.00%     29.17%
10     75.00%	  65.00%     55.00%	45.00%	   37.50%
12     79.17%	  70.83%     62.50%	54.17%	   45.83%

The probability of the attacker's die (down the column) beating the
defender's die (across the row)--
so if A is a 6 and D is a 10, we see that A has a 25% chance of beating
D.

If A has a Quality and Firepower roll, each d6, and needs to beat D's d10,
then the odds are:.25 *.25 = 6.25% both beat.75 *.75 = 56.25% neither beat
1 - (sum of results above) = 37.5% one beats

G'day,

Actually the links down... or at least it is for me (I'm using Netscape
4.77)

They're both up as far as I can tell, using IE5.5:
http://home.quixnet.net/~deboe/links/fmaodds.xls for the spreadsheet
http://home.quixnet.net/~deboe/links/fmaodds.htm for the page where I
would have put a coherent explanation, if I'd been coherent.

Of course, I also checked them before I send the message last night, so it
