A question on axiomatization of geometry

Does anyone have an idea if it is possible to prove Dedekind's continuity axiom from the list of Hilbert's axioms, as given in his book Grundlagen der Geometrie ? Especially what is the role of the
last completeness axiom in his list ?

You can derive E(Y^2) easily:
let f(x) = ƩC(m,x)*q^x * (1-q)^(m-x)
E(X^2) = ƩC(m,x)*x^2 *q^x * (1-q)^(m-x)
Observe that this is equivalent to ƩC(m-1,x-1)*(m/x)*q^x*(1-q)^(m-x)*x^2
This becomes:
