Does anyone know the keystrokes to calculate this problem on HP? Given the following probability distribution, find the standard deviation of expected returns. Event P(RA) RA Recession 0.10 -5% Below Average 0.30 -2% Normal 0.50 10% Boom 0.10 31%
When calculation expected return and standard deviation with probability like this case, you must use the formula manually. I think it is not so difficult.
that is what I thought. Thanks.
