Answer:
Standard deviation=11.82%
Step-by-step explanation:
Standard deviation is measure of the total risks of an investment. It measures the volatility in return of an investment as a result of both systematic and non-systematic risks. Non-systematic risk includes risk that are unique to a company like poor management, legal suit against the company .
Standard deviation is the sum of the squared deviation of the individual return from the mean return under different scenarios
Expected return (r) = (30% × 0.25 ) + (15% × 0.65) + (-14%× 0.10)=15.8%
Outcome (R- r )^2 × P
Boom (30%-15.8)^2× 0.25 = 50.05
Normal (15%-15.8)^2×0.65 = 0.47
Bust ( 13.6%- 15.8)^2 ×0.1= 89.10
139.63
Standard deviation =√139.63= 11.82%
Standard deviation=11.82%
