Thanks you too!

Homework Statement "You are now going to show that, in the Gaussian distribution P(x)=Ae^(-Bx^2) the constant A is equal to sqrt(B/Pi). Do this by insisting that the sum over probabilities must equal unity, Integral(P(x)dx)=1. To make this difficult integral easier, frst square it then combine...

This helps so much! Thank you!

In the formula, PN(n) = N!/(n!(N-N)!) (p^n)(q^(N-n)) N represents the number of elements, but what exactly does little n represent? Thanks for any help!

I am trying to solve for probabilities in systems with a large number of elements. To deal with the large factorials that appear in these formulas, I use Stirling's formula, lnm!=mlnm-m+(1/2)ln(2πm). My problem is that after I get the approximation and try to plug it into the probability...
