details The discovery that deterministic statements can be proved by probabilistic
reasoning, led already more than fifty years ago to several striking
results in various mathematical disciplines. It soon became clear that
the method, which is now called the probabilistic method, is a very
powerful tool for proving results in Discrete Mathematics.

After some brief light examples that illustrate the fact that
probabilistic arguments may be counter-intuitive, I will describe several
applications of probabilistic ideas in the design of efficient algorithms
and in the proofs of combinatorial statements.

The main theme is that a probabilistic point of view may be very helpful
even when we are interested only in purely deterministic algorithms,
or in purely deterministic mathematical statement.
