[09 cdfF (]: Finds the F distribution probability of specified range x for F distribution with
two independent degrees of freedom, m and n (cannot be entered using lists).
Format: cdfF (lower limit, upper limit, degrees of freedom of the numerator, degrees
of freedom of denominator) However, the degrees of freedom of the numerator and
the degrees of freedom of the denominator may be omitted.
<Example 9>
Find the probability of range “x = 0 to 2.5” for F distribution generated with degrees of
freedom 15 and 10.

* An error may occur when entering an extremely large number
(exceeding 100, etc.) for the degrees of freedom.
[10 pdfbin (]: Finds the probability density of specified value x for binomial distribution
(cannot be entered using lists, with the exception of success numbers).
Format: pdfbin (trial number, success probability, success number) However the
success number may be omitted (when the success number is not specified, the
calculation is executed by entering values from 0 to the trial number and displays
the list).
* The success probability is 0≤p≤1.
<Example 10>
There is a binomial distribution with success probability of 30%. Find the probability
density for 15 trials with “x = 7”.
