The coefficient of variation is a measure of variability that is computed as the ratio between the standard deviation and the mean of a probability distribution. You can think of it as a general measure of the relative breadth of a probability distribution. Since the square of the standard deviation is the variance of a distribution, this means that queues vary linearly with variance, a point worth remembering.

Random chance plays a huge part in everybody's life.

So much of life, it seems to me, is determined by pure randomness.
