I don't mean to be picky, but your formula doesn't solve the question exactly (your word). The poisson distribution is an approximation. In this problem the difference is as follows:
using # of hands = 28710 and prob of 4 deuces = 1/4900
exact answer using binomial distribution
(1-1/4900)^28710 = 0.28518...%
approx answer using poisson
(1/e)^(28710/4900) = 0.28535...%
Again, I mean no offense but when you said exactly I just wanted to point out that the poisson is an approximation. As we see, it is a very accurate one!

On my last trip playing about 20000 hands of NSUD, I got two real royals and no 4 ducks. So it happens.

??? FWIW
here is the complete equation for solving this problem exactly
(1/e)^6= 0.25% where e = 2.718 (natural log)
