uBinomial probability
Binomial probability calculates a probability at specified value for the discrete
binomial distribution with the specified number of trials and probability of success
on each trial.

(1–p)
n – x
(x = 0, 1, ·······, n) p : success probability
(0 < p < 1)
n : number of trials

The following shows the meaning of each item when data is specified using list
specification.
Data ................ data type
List .................. list whose contents you want to use as sample data
Numtrial .......... number of trials (positive integer)
p ..................... success probability (0 < p < 1)
Execute .......... executes a calculation
The following shows the meaning of a parameter data specification item that is
different from list data specification.
x ..................... integer from 0 to n
Example To calculate binomial probability for one list of data
For this example, we will calculate binomial probability for
data = {10, 11, 12, 13, 14} when Numtrial = 15 and success
probability = 0.6.
