Hungarian mathematician George Polya proved back in 1921 that anyone who gets lost can eventually get home by simply tossing a coin to decide which way to go next.
Polya explained that the main point of the admittedly somewhat complex Bayes theorem, which has as many as a dozen symbols, is contained in its simple corollary, "A theory is confirmed by its consequences.

Help your students apply the basic four-step problem-solving process developed by the late George Polya and described in his book How to Solve It: (1) understand the problem, (2) devise a plan, (3) carry out the plan, and (4) reflect on the problem and your approach.
Polya (1945/1973) argues that metacognition facilitates the development of the type of knowledge that is of particular value for "future mathematicians":
The research was done on programs that employ heuristic reasoning, a term defined by George Polya, a Stanford mathematician, as the art of good guessing.
Finally, Price (1976) suggests that the "cumulative advantage distribution," which can be derived from a modification of the Polya Urn model (see Feller [1968]), [2] provides a sound conceptual basis for the statistical modeling of the situation in which "success breeds success.
