8) 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.
