Web29 de fev. de 2016 · Here n is 100 and p is 0.15 (which is not close to 0.5). In this case, the exact answer is 0.0663. The normal approximated answer is 0.06178 and the Poisson approximated answer is 0.08297. My doubt is that, since p is closer to zero than it is to 0.5, shouldn't the Poisson approximation yield a better answer?
