Simulated 2-Spinner Data submitted by: Jeff LeMieux, June 2003 This narrative describes how I use my javascript tool, cataloged in the Math Tools digital library, in the classroom. Course: Math 7 Topic: Probability, Experimental Probability Resource type: JavaScript Resource location: http://www2.whidbey.net/ohmsmath/webwork/javascript/spinnerx.htm Math Forum catalogue entry: http://mathforum.org/mathtools/tool.html?rc=tool&new_id=784 Story:  The script for two spinners allows students to investigate the situation where the number of outcomes for the two events can be changed to diffeent values. Using a coin and a die locks the experiment into a single pattern. By changing the number of segments of the spinners allows students to practice with determining outcomes and the fundamental counting theorem. Students still have to count the outcomes and record their data. This script allows for two spinners with up to 6 segments each. Where and how I used this:  This script is used at the end of the introduction to probability of independent events. From this point students should have enough familiarity to determine their own experiments using things like tetrahedral dice, decks of cards, drawing slips from a hat, etc. Normally, at this point in the lesson we talk about how many license plates yu can make, state lotteries and in general set up for the probability of dependent events.
