(1) What probability model is appropriate for modelling the number of customers per week, and what value(s) should the parameter(s) have? (ii) What is the probability of getting exactly 50 customers this week? (You don't need to simplify your answer.) (i) The gap between customers (the length of time between one customer arriving and the next customer arriving) can be modelled as an exponential random variable with parameter value i = 1 hour. One customer just arrived. What is the probability of the next customer arriving in the next 30 minutes? (You don't need to simplify your answer.)
