  What is the percentage chance that Saurus Cold-One Riders will fail their stupidity roll? They have an 8 LD and roll 3D6, discarding the highest.

It's easy when you realize that means that two of the dice be 5 or 6. The chance is about 11%.

9+ on 3D6 (drop highest) = 23
Total possible rolls on 3D6 = 216

Prob = 23 / 216 * 100 = 10.65%

Right? I dropped duplicates from the rolls for the first number, but I just used 6*6*6 for the possible rolls. Is there more to the second number than that?

Nope.  23/216 is the correct probability of rolling three dice where at least two must be 5 or 6.

Thanks guys!

In comparison, a Druchii chariot has about 28% of failing its Stupidity on Ld8 and Cold One Knights fail 1/6 of the time on Ld9.

So what happens when a scar veteran with the +1 lds helmet joins the bunch? :p
Then you need to roll a 10+ for them to go stupid, i think that's a possibility of 15/216= 6.94444444...%

the helmet is only for skinks, which sucks because that stupidity test is a pain. Pity that it's not just that you lose the mount's attack or something.

This makes me very sad. :(
