Answer:
3.566%
Step-by-step explanation:
The probability formula for a poisson distribution is:

λ is the average of events
e is the euler's number
k is the number of events you want to know the probability
For this :
λ = 8.9 (on average the number of tickets is 8.9 per day)
k = 4 (you need to find the probability that exactly 4 tickets are written per day)

Perimeter: 36
5n + 3 = 36
5 · 6.6 + 3 = 36
N = 6.6
------------------------------------------
Perimeter: 36
1/4n + 2 = 36
1/4 · 136 + 2 = 36
N = 136
Hopefully i understood the question correctly :) Hope this helps
