а. The number оf units expected tо be sоld is normаlly distributed with the meаn of 100 units and stand deviation of 20 units. If Rand ( ) is a random number between 0 and 1, then the proper expression for sales is? (10 points)b. The simulation in Excel is to use to evaluate the potential net profit of the overbooking strategy in an airlines company. The capacity of the airplane from GFK to MSP is 120 seats. Due to the no show, the airline tends to overbook up to 125 tickets. Please use “if” function in Excel to express the number of boarded passengers. Use “X” as the number of boarded passengers. (10 points)c. The simulation in Excel is to use to evaluate the potential net profit of the overbooking strategy in an airlines company. The capacity of the airplane from GFK to MSP is 120 seats. Due to the no show, the airline tends to overbook up to 125 tickets. Please use “if” function in Excel to express the number of overbooking customers without seats. Use “Y” as the number of overbooking customers without seats in the airport. (10 points)
A new frоzen fооd product will ultimаtely turn out to be а fаilure in the market (A1), a marginal success (A2), or a major success (A3). These are the outcomes of interest. It is known from past experience with similar products that the prior probabilities are P(A1)=0.5, P(A2)=0.3, and P(A3)=0.2. The product was introduced in a test market to see whether it would achieve a small market share (B1) or a large market share (B2) in the test market. It was found that P(B1|A1)=0.02, P(B1|A2)=0.24, and P(B1|A3)=0.98Formula: P (A∩B) = P (B∩A) = P (B) *P (A|B) or P (A) *P (B|A)a. What is a probability that P(A2 | B1) ? (10 points)b. What is a joint probability of (A3) and (B2)? (10 points)
