Density of the Poisson distribution

In this exercise you'll find the probability that a Poisson random variable will be equal to zero by simulating and using the dpois() function, which gives an exact answer.

Instructions

100 XP

Simulate 100,000 draws from a Poisson distribution with a mean of 2.
Use this simulation to estimate the probability that a draw from this Poisson distribution will be 0.
Find the exact probability that a draw from a Poisson(2) distribution is zero, using the dpois() function.
