You can put this solution on YOUR website! 6 or more complaints a day with lambda=4
This is 0.2149
calculator 1-Poissoncdf(4,6)
The Poisson distribution is calculated from the left, so do 1- which will be the complement.'
Can check by using poissonpdf for (4,0) through (4,5) and subtract that from 1.
