u u u u u Binomial probability
Binomial probability calculates whether data taken from a binomial distribution is
less than a specific value.

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 <
Execute .......... executes a calculation
The following shows the meaning of parameter data specification items that are
different from list data specification.
x
..................... integer from 0 to
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.
