Consider the probability distributions of the first year cash flows of projects, GHI and JKL :

GHI Possible cash flow	JKL Probability
-$5,000	30%
$0	30%
+$7,000	40%

(a) Calculate the range of possible cash flows for each project

(b) Calculate the expected cash flow for each project

(c) Calculate the standard deviation of the possible cash flows for each project

(d) Calculate the coefficient of variation of the possible cash flows for each project
