Buckeye Brewery determines that its liability losses have the following distribution:

Loss	Probability
$ 4,500	0.03
$ 3,000	0.07
$ 1,500	0.15
$ 600	0.30
$ 0	0.45

A. Graph/Sketch the probability distribution. (

B. (Calculate) What is the expected value of the liability losses? (

C. (Calculate) What is the variance and standard deviation of the liability losses?

D. Explain why variance and standard deviation are useful measures of risk.

E. Using your graph from part A, comment on the skewness of the liability losses.
