Answer:

3.566%

Step-by-step explanation:

The probability formula for a poisson distribution is:

P( k )=\frac{\lambda^{k}e^{-\lambda}}{k!} \\

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)

P( k=4 )=\frac{8.9^{4}e^{-8.9}}{4!}=0,03566 =3.566\%
