Defined model

A carbon-14 atom decays within a million years

Probability:
(100 − 2.91 × 10⁻⁵¹)%
Odds:
(3.43 × 10⁵²) to 1
dBan
+525.4 dBan

With a half-life of 5,730 years, the cumulative probability that one carbon-14 atom decays during the next million years is extremely close to one.

Calculation

p = 1 − 2⁻ᵗ⁄ᵀ½, with t = 1,000,000 years and T½ = 5,730 years

Assumptions

The model uses a constant exponential decay rate over the full interval. About half of a large group of carbon-14 atoms would decay within 5,730 years.
