Covid-19 ward nurses worry about the number of arriving patients in their ward. In a typicalhospital, the nurses cannot accept arriving patients if there are more than 10 Covid-19 cases in agiven hour. It is assumed that patient's arrival follows a Poisson process, and historical datasuggest that, on the average, 5 cases arrive per hour.What is the probability that in every two hours the nurses cannot accommodate the arrivingpatients?a. 0.4170O b. NONEO c. 0.5830d. 0.0137 Walmark randomly draws 5 different gift vouchers to be given to selected loyal customers eachday. For today, they draw the $5 gift voucher. What is the expected number of days until this giftvoucher is again drawn? What is the probability that this gift voucher is again drawn exactly 5days from now? Let X denote a geometric random variable. (Show solutions)O a. E(X) = 10 days, P(X-5) = 0.0819O b. NONEc. E(X) = 5 days, P(X-5) = 0.0819O d. E(X) = 5 days, P(X-5) = 0.0656

QUESTION 3 H Profits for a skiing resort depends on how much snow falls in winter. The probability distribution of snowfall and resulting profitability is as follows: More than 40 inches K120 000 40% 20 to 40 inches K40 000 20% Less than 20 inches -K40 000 40% The owner receives an offer from a hotel chain to lease the resort at a guaranteed profit of K45 000 for the season. He is also considering leasing snow making equipment which would allow the resort to operate full-time regardless of the amount of natural snow fall which would ensure profit of K120 000 minus the cost of leasing and operating the snow equipment. The leasing cost is K12 000 per season regardless of usage. Operating cost will be K10 000 for natural snowfall of more than 40 inches, K50 000 for between 20 and 40 inches and K90 000 if it is less than 20 inches. Required: Construct a decision tree…

A barbershop is operated by one barber and has a space capacity to accommodate for a total of 6 customers (including the one in service). If a customer comes to this shop and finds it full, he goes to other shops. Customers arrive according to Poisson distribution at a rate of 4.1 customers per hour. The barber’s service time is exponential and he can serve at a rate of 7.1 customers per hour. a. What is the probability that the barber is free? Answer = Answer b. What is the expected number of people in the system? Answer = Answer c. What is the expected waiting time in the queue? Answer = Answerhours. (hint: use effective arrival rate)
