Example: a person throws three dice. Suppose we are interested in cases, when two dice and when all three dice show the same number of eyes. We therefore define a function which assigns a value of three to the random variable in the case that all three dice show the same number of eyes, a value of two if only two dice satisfy the defined condition, and a zero value if this condition is not satisfied at all.
Hint: The terms random variable and random
number are often mixed up, although they have nothing in common except
the word "random".
