24		Mean Return	2.50%	1.69%	=AVERAGE(E4:E23)
25		St. Deviation	5.73%	6.23%	=STDEV.S(E4:E23)
26
27		Since the return of the stock is normally distributed, therefore
28		Norm.dist function of excel can be used to calculated the probability as follows:
29
30		Probability that the return is less than zero	=P(X<0%)
31			0.33	=NORM.DIST(0%,D24,D25,TRUE)
32
33		Hence the probability that the return is less than zero is	0.33
