Question

For an investment in a stock, the probability of the return being –10.0% is 0.3, 10.0% is 0.4, and 30.0% is 0.3. given the probability distributions, what is the expected rate of return for the investment

Answer 1

The expected return will be given by:
E(R)=Total sum of the expected return
E(R)=-0.1*0.3+0.1*0.4+0.3*0.3
E(R)=-0.03+0.04+0.09
E(R)=0.1=10%

We therefore conclude that the expected return is 10%
