Dr.Peterson replied to the thread combinatorics problem - discrete math.I said "possibilities for the hours", for which there are two digits. Isn't it clear that the hour can be 11 or 12, because and 1≤1 and... -
Steven G replied to the thread combinatorics problem - discrete math.@Dr.Peterson, I would think that each position could only contain 0-9. I am not sure what you mean by 11 and 12. Yes you can have... -
Dr.Peterson replied to the thread combinatorics problem - discrete math.I think it's fairly clear what the question means; I'm a little curious why, in H1 ≤ H2 ≤ M1 < M2 ≤ S1 < S2, two of the comparisons are...

JIt depends a bit on whether f^2(c)=(f\circ f)(c)=f(f(c)) is an option at all. The specific line looks more as if f^2(c)=f(c)^2 was...
