We know that expected returns as name suggests are returns which are expected to be earned.
00:07
Whereas standard deviation is the risk associated with the given portfolio.
00:12
Both are important for assessing a given portfolio.
00:16
Here in part a, we have to find the expected return of the portfolio.
00:25
Solving part a, we have to find the expected return of the portfolio which is calculated as e as.
00:34
Means expected return is equal to 0 .6 into es plus 0 .4 point into eb.
00:49
This is equal to 0 .6 into 10 plus 0 .4 into 8.
00:58
Solving this we will get 9 .2 % is the required value here.
01:06
Now we will solve part b.
01:15
Now we will find the variance of the portfolio.
01:19
Variance x is equal to 0 .6 square into variance of s plus 0 .4 square into variance of b plus 2 into 0 .2 into 0 .4 into 0 .6 into standard deviation of s into standard deviation of b.
01:51
This by putting the value you will get 0 .36 into 15 square plus 0 .16 into 12 .5 square plus 2 into 0 .2 into 0 .4 into 0 .6 into 15 into 12 .5.
02:17
Calculating this we will get 12 .4...
