For example, if I breed a P5iv HA Dratini holding an Everstone with a P5iv HA Dragonair holding a Destiny Knot, how do I calculate the % chance of getting a P5iv HA Dratini from an egg?
(Both are missing the SpA stat)

Are you using the Destiny Knot, power item, or both? Are both of the parents missing the same stat?
Sorry I forgot abt those

Because the Destiny Knot passes down 5 of the parents' stats at random, the best chance that you'll get a 5IV Dratini would be if the stat that is not passed down is the worst stat of the parents (in this case, SpA), which is a 1/6 chance, or 16.667%.
Honestly, you could probably stop here, but technically, for the 5/6 chance that one of the other stats is not passed down instead, there is still a 1/32 chance that the stat randomly rolls a perfect 31. For this, we multiply 5/6 by 1/32, which gives 5/192. You could get a 5IV either by the 1/6 chance or by the 5/192 chance, so for our final probability, we add them together for a 37/192 chance, or 19.27%.
