A random number or random variable is the result of a random process whereby the result is not deterministic. We can only know the exact value of the variable a posteriori, meaning after the fact. For example, the next roll of the dice is random. We only know the result after we roll them. A coin toss is also random. We only know which side it lands on after it is tossed. Another way to look at random variables is to consider the information they reveal. For example, while a student’s test score is fixed, ...
