Can anybody please solve and explain the concept? Thanks, An Investment has a mean return of 15% and standard deviation of returns equal to 10%. If the distribution of the returns is approximately normal, which of the following is least likely correct? The probability of obtaining a return A less than 5% is about 16% B greater than 5% is about 84% C greater than 35% is about 2.5% D between 5% and 25% is about 95%
“Approximately normal” implies 68% of the samples will fall within one deviation, 95% w/in two, and 99.7 w/in three. SO A B and C are correct - D is the least likely.
