normalpdf(
computes the probability density function (
) for the normal distribution at a
specified
x
value. The defaults are mean
m=0 and standard deviation s=1. To plot the
normal distribution, paste
normalpdf(
to the Y= editor. The probability density function
(pdf) is:
B:
binomcdf(
Binomial cumulative density
C:
poissonpdf(
Poisson probability
D:
poissoncdf(
Poisson cumulative density
E:
geometpdf(
Geometric probability
F:
geometcdf(
Geometric cumulative density
