At the town dog kennel, the number of dogs declared lost in a single day has the distribution of a Poisson random variable with mean 3 per day. What is the probability that during a given year(365 days) there will be at least 1000 dogs lost? Explain how to compute the answer using R or other programming language.

Can any one help me on solving this??? I just want to know how to compute if you are uncomfortable to R.
