OK so i was playing a RPG earlier today and was astonished at how many people couldn't understand that drop rates are not linear so I decided to create a simple formula as to how to determine %chance to drop after each kill.
I started with this:
a: percent to drop
ptd: means percent to drop (the acctual words not the number)
ptd 1k: a
ptd 2k: a+(1-a)a= 2a-a^2
ptd 3k: a+(1-a)a+[1-(a+(1-a)a]a
Now i know there's a pattern in there and I'm sure it has something to do with geometric series but I just cant define the pattern.
(I'm sure there's an easier way to do this question than my method and I would love to know it so I could give them a formula real fast but I am also curious as to how to find the pattern in these series)
^^Sorry for bad grammer up there if you didnt understand plz ask me to explain I will be looking back at this every hour or so.
