Carbon-14 dating, as described in the question above, does not work for samples that are very old (more than 50,000 years.) If an organism died 57,300 years ago, and the half-life of carbon-14 is 5,730 years, what fraction of the original carbon-14 in the sample would remain after that many half-lives? *
