You also calculate the standard deviation given this initial probability distribution. That number is

	a.	23.5%
	b.	18.2%
	c.	10.5%
	d.	45.2%

Now you turn your attention to estimating the likely returns on the project. You start with the probability distribution given by your primary consultant, which is in the Excel spreadsheet. The project's expected rate of return given these initial numbers is

	a.	7.99%
	b.	7.40%
	c.	7.18%
	d.	6.14%
