This distribution is useful in determining the probability that a single
observation falls within the range between the lower bound and upper
bound.

This distribution is useful in determining the probability of success in a
success/failure trial, at trial n. For example, you could use this distribution
to predict the probability of getting heads in a coin toss on the fifth toss.
Binomial Cdf (binomCdf())
the discrete binomial distribution with n number of trials and probability
p of success on each trial.
This distribution is useful in determining the probability of a success on
one trial before all trials are completed. For example, if heads is a
successful coin toss and you plan to toss the coin 10 times, this
distribution would predict the chance of obtaining heads at least once in
the 10 tosses.

This distribution is useful in determining the probability of obtaining a
certain number of successes before a trial begins. For example, you could
use this calculation to predict the number of heads that would occur in
eight tosses of a coin.
