1. The problem statement, all variables and given/known data An insurer uses the Poisson distribution with mean 4 as the model for the number of warranty claims per month on a particular product. Each warranty claim results in a payment of 2 by the insurer. Find the probability that the total payment by the insurer in a given month is less than two standard deviations above the average monthly payment. 2. Relevant equations 3. The attempt at a solution So, mean = 4 Standard deviation = 2 x=2 Will I use the density function to solve this?
