Permutation, Combination, Factorials And Random Number Generation - Canon F-570SG User Instruction

P(t): Probability below a
given point x
Q(t): Probability below a
given point x and above
the mean
R(t): Probability above a
given point x
Example: Calculate the probability distribution P(t) for the sample
data: 20, 43, 26, 46, 20, 43, 26, 19, 23, 20 when x = 26.
