The use of indicator functions is promoted as a vehicle for providing students with greater appreciation and understanding of the function concept, which might be good preparation for the functional concepts of probability and random variable. The use is seen to provide a reasonably accessible method of verifying set-theoretic statements. (MP)

Several common errors reflecting difficulties in probabilistic reasoning are identified, relating to ambiguity, previous outcomes, sampling, unusual events, and estimating. Knowledge of these mistakes and interpretations may help mathematics teachers understand the thought processes of their students. (MNS)

Outlines an approach to information retrieval which integrates the existing theory of probabilistic retrieval into a practical methodology based on Boolean searches. Basic concepts, search methodology, and examples of Boolean searching are noted. Twenty-six sources are appended. (EJS)

Two instructional methods, reception and discovery, together with a control condition, were compared in terms of their effects on the performances of kindergarten children (n=72) on probability tasks. Evidence for the superiority of discovery learning was not forthcoming. (Author/PN)

The game of Yahtzee is discussed in terms of the various outcomes of turns in the game and their point values and the probabilities associated with achieving specific combinations of dice values. Several tables and methods of table construction are noted, and several challenge exercises are included. (MP)

Hintzman's 1980 attack on certain analyses in memory research is based on doubtful presumptions, namely, that contingency tables are inherently suspect as evidence for or against scientific conclusions and that pressing this logical argument is in some way an acceptable substitute for empirically examining the conclusions in question. (Author)

Presents the game of Keno as an interesting, realistic model for applying mathematics that can be an excellent aid in teaching some basic probability concepts. It is felt that having students examine the probabilities may convince them that winning at Keno is unlikely, and it is an unfair game. (MP)

Various federal agencies and the courts are facing questions about the legality and potential discrimination in sex-segregated mortality tables and discrepancies in retirement and insurance benefits. By using unisex mortality tables, TIAA-CREF is an unwilling pioneer in the insurance industry, but the tables' ultimate form remains in question.…

The uses of random number generators are illustrated in three ways: (1) the solution of a probability problem using a coin; (2) the solution of a system of simultaneous linear equations using a die; and (3) the approximation of pi using darts. (MP)

The use of the randomized response technique as a tool of obtaining answers to sensitive questions is illustrated. Directions for two classroom experiments are included. (MP)

An alternative to the uniform probability distribution model for ordinal data is considered. Implications for statistics and for test theory are discussed. (JKS)

In this "thank-you" letter to Mr. Pascal, many applications for Pascal's triangle are pointed out. (MK)

A discussion is given on the probability of winning at the game of craps. Variations are discussed in terms of probabilities. (MP)

Analyzes the transmission coefficient for a completely general one-dimensional rectangular potential, or well, simply by concentrating on psi squared rather than psi. Gives graphs of all cases of psi squared. (Author/GA)
