Surjective Maps
Hello, let X, Y and I be three (non empty) sets and {f_i:X->Y} a family of distinct surjective maps indexed by I. Can you find distinct injective maps {g_i:Y->X} such that (f_i)°(g_i) is the identity map of Y for every i in I? Thank you very much for your attention. My Best Regards, Mury Barbato PS Note t... 18 Feb 2010 10:35

Is Pascal's Triangle related to the Normal Bell Curve?
I noticed that when I plot the numbers on a given row of Pascal's Triangle, the curve generated resembles the Bell Curve. However, what distinguishes the Pascal's Triangle to the Normal Gaussian Distribution Curve is this: When I divide the biggest number (which is in the center of Pascal's Triangle) by the SUM ... 24 Feb 2010 13:09

Marbles and jars - easier/closed form?
Given M marbles to be randomly put in N jars, I needed the probability that at least one of the jars remains empty. With some inclusion/ exclusion, I seem to get a correct result : P(M,N) = sum(binomial(N,i) * (1 - i/N)^M * (-1)^(i+1),i=1..N-1) I was wondering if there is a more closed form of this result (and... 17 Feb 2010 00:25

two most famous and important proofs in all of mathematics-- Pythagoras & AP-finite-selection #437 Correcting Math
There is one point of contention. I am not sure if it is a one-to-one correspondence, or just a correspondence. Anyway, it is no loss to the proof for we simply correspond one endpoint of the line-segment with the associated endpoint of a line-ray. So what line-segment, the largest line-segment is associated with... 17 Feb 2010 00:25
