The phоtо bоoth mаchine аt Columbiа Mall takes a series of snapshots in exactly 1.5 minutes. Customers arrive at the machine according to a Poisson distribution at the mean rate of 24 per hour. On the basis of this information, determine the following: (you must show how you get the answers.)The average number of customers waiting to use the photo machineThe average time a customer spends in the systemThe probability an arriving customer must wait for service.

Thоmpsоn Reаl Estаte Cоmpаny in Grand Forks is to consider constructing an apartment complex for renting. There are three alternatives and their payoffs as the table shown. The probabilities of the chance events now are 60 % for favorable market and 40% for unfavorable market. Decision AlternativeState of Nature: Favorable Market ($)State of Nature: Unfavorable Market ($) Construct Large complex400,000-360,000 Construct Small complex200,000-50,000 No Plant at all00Before deciding about building a new complex. The company has the option of conducting a marketing research survey, at a cost of $20,000. The company understands that a market survey will provide sample information, but it may help quite a bit. The market survey will come out either Positive or Negative. Following four conditional probabilities were known.P (survey positive | FM) = 0.7 P (survey negative | FM) = 0.3P (survey positive | UM) = 0.2P (survey negative | UM) = 0.8P (FM) = 0.6P (UM) = 0.4Formula: P (A∩B) = P (B∩A) = P (B) *P (A|B) or P (A) *P (B|A)a. Calculate marginal probability of Survey Positive and Survey Positive? P (survey positive) and P (survey negative).b. Calculate conditional probabilities: P (FM | survey positive) and P (UM | survey positive)c. Calculate conditional probabilities: P (FM | survey negative) and P (UM | survey negative)d. Calculate Expected Value of Sample Information, given EVw/o SI = 100,000
