WebWe end this section with a statement of the properties of cdf's. The reader is encouraged to verify these properties hold for the cdf derived in Example 3.2.4 and to provide an intuitive explanation (or formal explanation using the axioms of probability and the properties of pmf's) for why these properties hold for cdf's in general.

In statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable. The general form of its probability density function is The parameter is the mean or expectation of the distribution (and also its median and mode), while the parameter is its standard deviation.
