normalpdf(
normalpdf( computes the probability density function (pdf) 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
