Answer:
a. 6.7%
b. 0.6 and 0.4
Step-by-step explanation:
The computations are shown below:
a. Expected rate of return = (Probability 1 × Possible Returns 1) + (Probability 2 × Possible Returns 2)
= (0.50 × 0.11) + (0.50 × 0.024)
= 0.055 + 0.012
= 6.7%
b. Portfolio beta = beta of stock × weightage of stock + beta of risk free asset × weightage of risk free asset
0.63 = 1.05 × weightage of stock + 0
So, Weightage of stock = 0.6
And, the weightage of risk free asset is 0.4
