Fundamental Formula of Gambling

Hi guys, I have a question...
I have this formulae:

log(1 - DC)
N = ----------------
log(1 - p)

I can find N if I have DC and p.
But I can't figure out how to find DC if I have N and p.
Is that possible?

Cheers!

Re: Fundamental Formula of Gambling

log(1 - DC) = N(log(1 - p))

Assuming base 10...

1 - DC = 10^[N(log(1 - p))]

etc.

Another approach uses the fact that log(1 - DC)/log(1 - p) = log(1 - DC) using base (1 - p).

log(1 - DC) = N log(1 - p) = log((1 - p)^N), so DC = 1 - (1 - p)^N.
