I guess that you can represent it by a Poisson since N is large. I think that a Binomial( 1.859E-7, 19million) would describe X more accurately.

If it were a binomial, then the expected value would be np = 19mil*1.859e-7. Your Poisson needs to have the same expected value, and since Poisson has only one parameter, lambda, which represents both the expected value and the variance, you know the answer.

Without knowing what "(m, t)" means, I don't see how anyone can help!
