We have been told that in history, the one-year returns follow approximately the normal distribution. Given that the one-year return for the S&P 500 was +27% (that is, 0.27) and its S.D (standard deviation) is 20% (that is, 0.2). (i) Determine the probability that a stock in the S&P 500 gained 30% or more last yearrrrr? (ii) DEtermine the probability that a stock in the S&P 500 lost 10% or more last year? (iii) Determine the probability that a stock in the S & P lost 14% or more last year?
