1. In this lab, we use the flipping of 200 pennies to simulate radioactive decay. sample in nature, there are many trillions of atoms undergoing radioactive decay. In the case of
natural samples, what fraction of atoms will remain after one half-life? Write a mathematical
expression(s) or describe in words (diagram) how you would relate the fraction of radioactive
atoms remaining to the number of half-lives that have elapsed in natural samples.
