Suppose two random variables X and Y are both zero mean and unit variance. Furthermore, assume they have a correlation coefficient of P . Two new random variables are formed according to:
W = aX + bY,
Z = cX + dY.
Determine under what conditions on the constants a, b, c and d the random variables W and Z are uncorrelated.
