WebThe basket that contained 25 % \% % of carbon-14 has passed 2 half-lives. To get the age of the basket, the half-life of carbon-14, which is 5,730 years, is to be multiplied to the number of half-lives it has passed. WebThis probability amounts to 50% for one half-life. In an interval twice as long (2 T) the nucleus survives only with a 25% probability (half of 50%), in an interval of three half-life periods (3 T) only with 12.5% (half of 25%), and so on.
