The decision to draw another card or stand pat in blackjack can be made by computing two simple probabilities. (MP)

A sequence of numbers from combinatorial theory called the Bell numbers is discussed, along with several problems and examples that demonstrate their usefulness. (MN)

Dr. Varga's description of the beginning of the Hungarian Project (primary mathematics) is recorded along with two examples of assignments to generate exploration and discussion involving probability. (MN)

The major intent of this research was to provide a further test of the relationships between physiological arousal and event probability by experimentally generating subjective expectancies for shock. The relationship of event probability to stress was discussed with respect to length of the anticipatory periods and methods used to establish…

Characteristics of the number seven, which relate to many different areas of mathematics, are discussed. (JT)

Investigates which formal principles govern subjective probability, and whether the validity of these principles depends on age. Results indicate that these principles are valid as principles of subjective probability for all age groups. (RWB)

Used four case studies of planned change to evaluate the effectiveness of the Probability of Adoption of Change model in predicting the probability of successful program implementation in higher education. Results provide support for the role of the variables defined in the model. (ABL)

Comments on E. G. Creamer and Don G. Creamer's article "Predicting Successful Organizational Change: Case Studies." Notes leadership placement in student affairs is logical but unfortunately not probable if the change is institutionwide. Raises questions about the conclusions drawn, although states a liking for the model. (ABL)

Discusses how the discovery of chaos has created a new paradigm in scientific modeling and how findings are contributing to changes in thought about many different branches of science. Includes explanations and examples of how chaotic behavior can be understood. (ML)

A realistic problem is presented, computing the probability of winning a sports playoff series if the probability if winning a single game is known. Only simple permutation formulas and some basic logic are required to solve the problem. Two computer programs and a discussion of solution methods are included. (MNS)

Suggestions for five activities are presented. They include: ideas for several student problem-solving projects; preparing a flowsheet and program for 10 coin and dice games; using word processor formatting commands to create word designs; creating sounds; and writing a program to print out sums indefinitely. (JN)

Explains an application of matrix algebra which involves probability matrices and weather predictions. Using probabilities of sunny or cloudy weather students can determine the effect weather on day one will have on subsequent days. (DH)

Four answers to a probability problem involving a perceived coincidence are discussed. (MNS)

Identifies key questions concerning children's intuitions and conceptions of probabilistic notions. Research on the theoretical framework for probability studies, misconceptions and strategies, and pupil attainment is reviewed, and the methodology is evaluated. Finally, implications for classroom practice are discussed. (MNS)

A random arrangement of two contrasting colors in a 20x20 array is used to facilitate students' understanding of the notions of randomness, independence, and long-run frequency. It can also be used to test some prevalent errors in probabilistic reasoning. Three activities are described. (MNS)
