revised What is the intuition behind $P(X={\lambda})\ {\equiv}\ P(X={\lambda}-1)$ for a Poisson distribution
added condition that lambda minus 1 be a nonnegative integer

@nrpeterson Thank you. I'll explicitly add the condition that lambda is a nonnegative integer.

comment Can a finite sum of square roots be an integer?
If you choose only integers that are squares of other integers this will always work, since their square roots are integers and the sum of a finite number of integers is an integer.
