2. the poisson paradigm is a heuristic rule of thumb. it says that if there are a very large number of chances for a certain thing to happen, but each individual chance is very unlikely, then the total number of occurrences will approximately have a poisson distribution. for example, suppose you have a 100-sided die and roll it 300 times. let xbe the total number of times you roll a 1. the exact distribution of xis bin(300,0.01), since there are 300 independent trials each with success probability 0.01, and e(x)
