[edit] Odd percentages
25% with Blind Fighting? That's not how probability works, is it? If you get a second roll with the same chance of missing (50%), the total chance of hitting is still 50%. You get two 1 in 2 chances of hitting. Together, that makes a 2 in 4 chance of hitting. 50%. 84.28.178.18 12:27, 3 May 2009 (UTC)
- No you get a reroll only if you fail the first roll. Thus to succeed you have the initial 50% success and then 50% of the remaining 50% for when the reroll succeeds. 50% + 25% = 75% success and thus 25% failure. Or you can see it as to fail with blind fight both the first roll and the second roll must fail. Thus it is 50% failure * 50% failure = 25% failure. WhiZard 17:00, 3 May 2009 (UTC)
- Another way to look at it is that you do not get a 2 in 4 chance of hitting. The 4 possible outcomes are hit-hit, hit-miss, miss-hit, and miss-miss, and you only miss if both outcomes are misses. That is, there are 3 of 4 outcomes that involve hitting. --The Krit 22:28, 17 May 2009 (UTC)
