      Normal distribution The normal distribution is the most widely known and used of all distributions. Because the normal distribution approximates many natural phenomena so well, it has developed into a standard of reference for many probability problems.

      A Normal distribution is described by a Normal density curve. Any particular Normal distribution is completely specified by two numbers: its mean 𝜇 and its standard deviation 𝜎. The mean of a Normal distribution is the center of the symmetric Normal curve. The standard deviation is the distance from the center to the change-

      The normal distribution is a common model of randomness. Unlike the uniform distribution, it proposes a most probable value which is also the mean, while other values occur with a probability that decreases in a regular way with distance from the mean. This behavior is mathematically very

      2 The Bivariate Normal Distribution has a normal distribution. The reason is that if we have X = aU + bV and Y = cU +dV for some independent normal random variables U and V,then Z = s1(aU +bV)+s2(cU +dV)=(as1 +cs2)U +(bs1 +ds2)V. Thus, Z is the sum of the independent normal random variables (as1 + cs2)U and (bs1 +ds2)V, and is therefore normal.A very important property of jointly normal random ...
