Poisson Distribution Calculator
All you need to know about Poisson Distributions
is the Poisson Probability formula.
Advanced Information on the Poisson Distribution: Mean = λ , Standard Deviation = λ
Sample Poisson Distribution Problem
What is the probability of Teddy scoring 2 goals, when on average he scores λ=2.5 goals per game?
Here, x=2 (the number of successes) and λ=2.5
Plugged into the Poisson Probability formula: P(X=2)= 2.52*e(-2.5)/ 2! = 6.25 * e(-2.5) / 2 = 0.2565 = 25.65%
