(2) What is the probability of having a return lower than -2.33 standard deviations?
a) 5%
b) 2%
c) 1%

(3) What is the kurtosis of a normal distribution ?
a) 3
b) 0
c) -3

(4) Which is the less dangerous for a risk averse investor?

(1) Skewness>0
(2) 1%
(3) 3
(4) Positive skewness with kurtosis>3
(5) 2822 years (i.e. [1 / normdist(-5%, (1+10%)^(1/12)-1,5%/12^0.5,1)] / 12 )
(6) 98%. This means you made 98% in 6 months.
