1A20.20 - Statistics and Probability - Coin Flip

Code Number:
Demo Title:
Statistics and Probability - Coin Flip
Unit of Measure
Area of Study:
Hand Full of Pennies.

Take a hand full of pennies and toss them into the air.  Probability predicts that half of them will be heads and half of them will be tails when they come to rest on the table.  The more runs you average together, will bring you closer to a 50:50 ratio.
