The Exponential Distribution (Optional) · Exercise 22
Carbon-14 is a radioactive element with a half-life of about 5,730 years. Carbon-14 is said to decay exponentially. The decay rate is 0.000121. We start with one gram of carbon-14. We are interested in the time (years) it takes to decay carbon-14.
What is the decay rate (m)?
This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
