Question 3

The head of operations for a movie studio wants to determine which of two new scripts they should select for their next major production.(Due to budgeting constraints,only one new picture can be undertaken at this time.)She feels that script #1 has a 70 percent chance of earning about $10,000,000 over the long run,but a 30 percent chance of losing $2,000,000.If this movie is successful,then a sequel could also be produced,with an 80 percent chance of earning $5,000,000,but a 20 percent chance of losing $1,000,000.On the other hand,she feels that script #2 has a 60 percent chance of earning $12,000,000,but a 40 percent chance of losing $3,000,000.If successful,its sequel would have a 50 percent chance of earning $8,000,000,but a 50 percent chance of losing $4,000,000.Of course,in either case,if the original movie were a "flop",then no sequel would be produced.What is the probability that script #1 will be a success,but its sequel will not?

Question 14

One local hospital has just enough space and funds presently available to start either a cancer or heart research lab.If administration decides on the cancer lab,there is a 20 percent chance of getting $100,000 in outside funding from the American Cancer Society next year,and an 80 percent chance of getting nothing.If the cancer research lab is funded the first year,no additional outside funding will be available the second year.However,if it is not funded the first year,then management estimates the chances are 50 percent it will get $100,000 the following year,and 50 percent that it will get nothing again.If,however,the hospital's management decides to go with the heart lab,then there's a 50 percent chance of getting $50,000 in outside funding from the American Heart Association the first year,and a 50 percent chance of getting nothing.If the heart lab is funded the first year,management estimates a 40 percent chance of getting another $50,000,and a 60 percent chance of getting nothing additional the second year.If it is not funded the first year,then management estimates a 60 percent chance for getting $50,000,and a 40 percent chance of getting nothing in the following year.For both the cancer and heart research labs,no further possible funding is anticipated beyond the first two years.What is the expected value for the decision alternative to select the cancer lab?
