Answer:
10.00%
Step-by-step explanation:
The expected return is the weighted average of all the returns recorded thus far wherein the probability of each return occurring is used as the weight of each return as shown below:
Expected return=sum of (weight* value of return)
Expected return=(7%*1/3)+(13%*1/3)+(10%*1/3)
Expected return=0.023333333 +0.043333333 +0.033333333
Expected return=10.00%
