The probability that you don't any step is: 7/8*5/6*26/27*11/12 = 5005/7776
So the probability that you skip at least one step is: 1-5005/7776 = 2771/7776 ~ 35.6% Sven --- In [email protected], "Mike Bennett" <[EMAIL PROTECTED]> wrote: > > --- In [email protected], "Stefan Pochmann" > <[EMAIL PROTECTED]> wrote: > > > > --- In [email protected], "Mike Bennett" > > <[EMAIL PROTECTED]> wrote: > > > > > > OE, PC, OC, PE. 1/8 + 1/6 + 1/27 + 1/12 = 89/216 (~41%) > > > > > > And if that's wrong, I'd like to blame my 4th grade teacher. ;) > > > > For 4x4 reducing it to 3x3, you have those two parity problems.
