I'm not quite sure how to calculate this, so I'd appreciate a little help.
30% scrolls pass at a 30% rate, fail at a 35% rate, and break at a 35% rate.
The % chance of passing 4 30% scrolls in a row is 0.0081, or 0.81%.
What is the chance of passing at least 4 30%s, in the first 5 slots? That is, 5 slots are used, one of them can fail but not break, but 4 must pass? 6 slots? 7 slots?
For all of the above questions, how many scrolls would it take to achieve this result, on average? How many equips would it take on average?
