can this be found? or is there not enough information?

Question

Let X be a random variable that represents the number of accidents at an intersection and assume X has a Poisson distribution within mean of 3.8 accidents per month what is the mean number of accidents per year?

Answer 1

Yes, it can be found. If there are 3.8 accidents per month, and there are 12 months in a year... And you remember that, in a Poisson distribution, the mean equals the variance...
