Answer:
12%
1.00
Explanation:
Note that the expected return on stock A which is 12% is missing from the question as well as the standard deviation of A which is 1.00
The expected return from stock A with 100% of funds(total amount of investment) invested in stock A is the percentage invested in A multiplied by the expected return of stock A shown thus:
expected return=100%*12%
portfolio expected return=12%
portfolio standard deviation(if 100% invested in A)=1.00*100%
