John is trying to decide whether to expand his business or not.
if he continues his business as it is, with no expansion, there is a 50 percent chance his revenue will be $100,000 and a 50 percent chance his revenue will be $300,000.
if he does expand, there is a 30 percent chance his revenue will be $100,000, a 30 percent chance his revenue will be $300,000 and a 40 percent chance his revenue will be $500,000. it will cost him $150,000 to expand. if john were to expand, which of the following is true?
a. john's expected revenue is $50,000 less than if he didn't expand.
b. john can expect to earn $120,000 in revenue more by expanding, but that is less than the cost of expansion, $150,000.
c. john can expect to earn $120,000 in revenue more by expanding and therefore made the most profitable decision.
d. all of these statements are true.

B) John can expect to earn $120,000 in revenue more by expanding, but that is less than the cost of expansion, $150,000.

Explanation:

If John decides not to expand his expected revenue will be = ($100,000 x 50%) + ($300,000 x 50%) = $50,000 + $150,000 = $200,000

If John decides to expand his expected revenue will be = ($100,000 x 30%) + ($300,000 x 30%) + ($500,000 x 40%) = $30,000 + $90,000 + $200,000 = $320,000

If John decides to expand, his revenue will increase by $120,000.

Since we are not told if John's revenue is yearly or not, I assume that it includes a whole business or project cycle. The cost of expanding is $150,000 while the incremental revenue is only $120,000.

there's 11 people for the 1st position. then, no matter who gets it, there's only 10 left for the second, and then 9 left for the third. 11 x 10 x 9 = 990.   the answer is there are 990 different ways the positions can be filled by these applicants
