hello I really need help with these exercises :(:(. Thank you in advance!


2. Assuming the mean number of customers who arrive per minute at the bank during the 1pm to 2pm hour is equal to 5.5 and follows Poisson distribution. What is the probability that in a given minute:
a) Exactly 3 customers will arrive?
b) And what is the probability that more than two customers will arrive in a given minute?

this is just something i need to pass , and english is not even my first language ( and I do not live in english-speaking country) so even if i had thoughts about it I would not be able to share them with you so please helpp
