Answer:
Madesimo is a famous resort in Italy. All of its rooms are always booked in the winter season and there are, on average, 180 skiers coming to the resort every day.
However, By using little law we have,
Average no of customers L = λW
Arrival λ = 180 per day
Arrival λ = 180/24
Arrival λ = 7.5 per hours
Waiting time W= 12days
W = 288 Hrs.
L = 7.5 × 288
L = 2160 Customers
