Let X be a normal random variable with mean Āµ, variance^2 , pdf and mdf
A random variable X is lognormal if ln X, the natural logarithm of X, is normally distributed. Find the mean and variance of a lognormal random variable with ln X ā¼ N(Āµ, Ļ2 ). [Hint: consider using the mgf of the normal distribution.]
Prove that any two independent random variables are uncorrelated.

Help with Pascalās triangle and binomial coefficients
Let X be a discrete random variable with probability function f(x). Prove that E[a + b g(X) + c h(X)] = a + bE[g(X)] + cE[h(X))], where g and h are functions, and a, b and c are constants.
Let a random variable X have the p.f. f(x) = c(|x| + 1)2 for x = 0, Ā±1. Find the constant c so that f(x) is a valid probability function. Then, find E(X), E(X2 ) and var(X).
Let X be binomial with parameters n and p. Evaluate E{X(X ā 1)} from first principles (i.e. the definition of expectation), and hence, derive var(X). You may assume linearity of expectation, and that E(X) = np.
