  A popular scientific contribution should not contradict any established facts
and ought to be understandable. I complied with both these requirements and am
offering a sufficiently full introduction to probability theory. Furthermore, I
enlivened my text with much information about the history of probability and
commentaries on the occurring notions which do not belong to that theory.
Indeed, a student is not a container to be filled but a torch to be kindled. I
hope therefore that my piece will essentially benefit beginners, be also
methodically useful to advanced readers, and even attract some inquisitive
people to probability.
