13 cdfpoi( cdfpoi(
mean, value
)
Finds the probability of a specified range x for a Poisson distribu-
tion of mean mu.
Example
Find the probability within the
range up to x = 4.
14 pdfgeo( pdfgeo(
success probability, value
)
Finds the probability density of a specified value x for the geomet-
ric distribution.
Limitations:
Success probability is 0 ≤ p ≤ 1.
Example
Find the probability density of a
geometric distribution of
success at the 26th time with
success probability of 5.6%.
15 cdfgeo( cdfgeo(
success probability, value
)
Finds the probability of a specified range of x for the geometric
distribution.
Limitations:
Success probability is 0 ≤ p ≤ 1
Example
Find the probability for the
range up to x = 26 with success
probability of 5.6%.
