a.
Answer to Problem 20P
The probability that the outcome will be between $16,800 and $31,200 is 0.8664.
Explanation of Solution
The calculation of the expected value (Z) for the outcome being equal to or greater than $16,800 is shown below.
The calculation of the expected value (Z) for the outcome being equal to or lower than $31,200 is shown below.

The calculation of the expected value (Z) for the outcome being equal to or greater than $14,400 is shown below.
The calculation of the expected value (Z) for the outcome being equal to or lower than $33,600 is shown below.
The Z values are positive as well as negative 2. Hence, the probability of the outcome being between $14,400 and $33,600 is 0.9544.

Answer to Problem 20P
The probability that the outcome will be at least $14,400 is 0.9544.
Explanation of Solution
The calculation of the expected value (Z) for the outcome being at least $14,400 is shown below.
The expected value is 0.4772 when Z is (+ or -) 2 and 0.5000 when Z is 0. So, the probability of the outcome being at least $14,400 is 0.9772. The graph of this probability is shown below.

Answer to Problem 20P
The probability that the outcome will be less than $31,900 is 0.9544.
Explanation of Solution
The calculation of the expected value (Z) for the outcome being at least $14,400 is shown below.
The expected value is 0.4505 when Z is (+ or -) 1.65 and 0.5000 when Z is 0. So, the probability of the outcome being at least $14,400 is 0.9505. The graph of this probability is shown below.
e.
To calculate: The probability that the outcome will be less than $19,200 or greater than $26,400.

e.
Answer to Problem 20P
The probability that the outcome will be less than $19,200 or greater than $26,400 is 0.4672.
Explanation of Solution
The calculation of the expected value (Z) for the outcome being less than $19,200 is shown below.
The expected value is 0.3413 when Z is (+ or -) 1 and 0.5000 when Z is 0. So, the probability of the outcome being less than $19,200 is 0.1587 (0.5000 – 0.3413).
The calculation of the expected value (Z) for the outcome being greater than $26,400 is shown below.
The expected value is 0.1915 when Z is (+ or -) 1 and 0.5000 when Z is 0. So, the probability of the outcome being at least $14,400 is 0.3085 (0.5000 – 0.1915).
Hence, the probability that the outcome will be less than $19,200 or greater than $26,400 is 0.4672. The graph of this probability is shown below.

Provide a short justification for vour answer. а) assets A, B, C, with expected returns and standard deviations: Suppose you are a mean-variance optimizer. The risk-free rate is 3%. There are three risky E [řA] = 10%, SD [řA] = 5% E [řB] = 15%, SD [řB] = 7% E [řc] = 12%, SD [ŕc] = 9% You cannot invest in all three risky assets. Instead, you have to choose whether to invest in only assets (A, B), or only assets (A, C). Asset B mean-variance dominates asset C, since it has higher return and lower standard deviation than asset C. Thus, as long as you are risk-averse, you would always prefer the set of assets (A, B) to the set assets (A, C). b) the same market B's.
