Hi there,
I am having a bit of trouble with a problem,
I am trying to find the sum from 4 to infinity of:
[ ((x-5)/x) * p(x) ]
where p(x) follows a poisson distribtuon of mean 6.
I have worked out how to do it on excel, however, I dont know if there is a more simple way of working this out?
Thanks from a first time poster
