Args: (x) Returns the value of the standard normal distribution function at X. Vectorized.
Args: (x) Returns the density at X of the standard normal distribution. Vectorized.
Args (p) Returns the P-th quantile of the standard normal distribution. Vectorized.
Args: (n) Returns a list of N standard normal random numbers. Vectorized.

The `utpn(x,m,s)' function uses a normal (Gaussian) distribution with mean `m' and standard deviation `s'. It is the probability that such a normal-distributed random variable would exceed `x'.

(BINOMIAL-PMF x n p)
The `k B' (`calc-utpb') [`utpb'] function uses the binomial distribution. Push the parameters N, P, and then X onto the stack; the result (`utpb(x,n,p)') is the probability that an event will occur X or more times out of N trials, if its probability of occurring in any given trial is P. The `I k B' [`ltpb'] function is the probability that the event will occur fewer than X times.
