Poisson Distribution
Can anyone help me with this question please? It's probably really easy but I'm having a blonde moment...
"The random variable X follows a Poisson distribution with standard deviation 2. Find P(X <= 3)"
The person who gives me the answer will get positive rep for the next 5 days
especially if they explain how they did it. Thank you
