Think of the classical example of something "random": the Gaussian
distribution. This is definitely NOT a case of all probabilities being
equal. There is a peak in the distribution at which the probability is
higher than at other values. What you are thinking of is a "uniform"
distribution, such as when you flip a fair coin or roll a fair die. Note
that if you roll two fair die, and calculate the probabilities of their
SUM, you no longer have a uniform distribution, but something closer to a
