Note: L1â99 and 1â99 specify infinity. If you want to view the area left of
upperbound , for
example, specify lowerbound = L1â99.
normalpdf( normalpdf( normalpdf( 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
