Assume the number of commuters using the QR code payment service at each MTR station follows a Poisson probability distribution. Based on a recent statistics, on average, 3 commuters use the QR code payment service in an hour. (i) What is the probability there are exactly 5 commuters who use the QR code payment service in an hour? (ii) What is the probability that there are less than 4 commuters who use the QR code payment service in 3 hours? (iii) If five MTR stations are randomly selected, what is the probability that at least two of the five MTR stations will have less than 4 commuters who use the QR code payment service in 3 hours?
