In the early 1970’s a remarkable connection was unexpectedly discovered between two very different fields, nuclear physics and number theory, when it was noticed that random matrix theory accurately modeled many problems in each. Random matrix theory was first used in the early 1900’s in the study of the statistics of population ...

If X is any random variable and c is any constant, then V(cX) = c2V(X) and V(X + c) = V(X) . Proof. We turn now to some general properties of the variance. Recall that if X and Y are any two random variables, E(X + Y) = E(X) + E(Y). This is not always true for the case of the variance.
