The author uses mathematical models that involve only algebra and a few basic ideas in discrete probability to describe the frequency of conception in large human societies. A number of calculations which can be done by students as exercises are given. (MN)

The author suggests several problems which can be investigated by beginning statistics students. All the problems discussed arise from the game Bingo. (SD)

After studying a unit on probability students "put it all together" by analyzing outcomes of real and computer-simulated games of craps. FORTRAN and APL programs for generation of the games are provided in this article. (SD)

The author gives a three dimensional analog of Pascal's Triangle as an exercise in heuristic thinking and an introduction to the multinomial theorem. The analog involves finding the number of shortest routes to various rooms in a cubical apartment house. (MN)
