Coin Toss Probability

1) Flip a coin 10 times, and record how many times it lands on heads or tails in the data table below. Then flip it 50 more times, and record the same information again. Finally, flip the coin 100 times, and record that data in your table.

2) Now use your data table to create a spreadsheet in Create a Graph. What do you notice about the numbers of heads and tails as you increase the amount of times you flip the coin?

3) Using your spreadsheet data, create a pie chart for each of your three sets of coin tosses. Tile each pie chart with the number of coin flips, and add the percentages as data labels for your charts.
