The study reports a subset of results from a larger investigation (Tarr, 1997) that sought to determine the impact of probability instruction of fifthgrade students' thinking during, immediately following, and seven weeks after a nineday instructional program in conditional probability. The primary objective of the present study was to determine students' strategies for describing conditional probabilities and how these strategies, which included the problematic use of '5050 chance', changed as the result of probability instruction.
