Normal distribution
param. ^ and o- gives P(X<x)
JLCT: 0 1
x: 1
The probability that a random variable is less than or equal
to 1 is calculated. The mean and the standard deviation is 0
and 1.
Rem. P(a<x<b)=P(x<b)-P(x<a) and
P(x>a)=l-P(x<a)

The Poisson distribution is used as a model when we are in-
terested in events within intervals of time or other variables.
