Question:

Suppose we are interested to study the number of customers arriving at a bank in a random work day. Previously we learned that the average number of customers per day is 100.

(a) Define a random variable X for the number of customers arriving in a random work day.

(b) Find the probability mass function.

(d) Derive the expected value (mean) of X based on the definition.

(e) What is the expected number of customers arriving in a random week of five working days?
