# Calculations of Probability: Assuming Poisson Distribution

A particular database gets hacker attempts at an average rate of 2.6 per month. Assume a Poisson distribution.

1. What is the probability of at least three hacker attempts during a month?

2. What is the probability of a hacker attempt occurring every 15 days or less (assume a 30 day month).
