Pie Graphs and ProbabilityDate: 09/21/2000 at 16:39:21 From: Kristine Pj Subject: Pie graphs and probability I don't know how to get the probability from a pie graph. Date: 09/21/2000 at 17:45:09 From: Doctor Ian Subject: Re: Pie graphs and probability Hi Kristine, A pie graph or pie chart tells you what fraction of the time something happened, or is expected to happen, and that's what probability tells you, too. In fact, a pie graph is just a way of drawing probabilities instead of writing them down using numbers. For example, suppose a pie graph has three areas, with people who will vote for Gore (41%), people who will vote for Bush (44%), and people who will vote for someone else (11%). This is like having 100 balls in a jar, with 41 marked 'Gore', 44 marked 'Bush', and 11 marked 'other'. So the probability that you'll pull a 'Bush' ball out of the jar is 44/100. I hope this helps. Write back if I didn't quite answer your question, or if you have other questions. - Doctor Ian, The Math Forum http://mathforum.org/dr.math/ |
