Suppose we consider a large number of continers each containing initially `10000` atoms of a radioactive material with a half life of `1` year. After `1` year.

Options

A. All the containers will have `5000` atoms of the material
B. all the container will contain the same number of atoms of the material but that number will only be approximately `5000`
C. the containers will in general have different numbers of the atoms of the material but their average will be close to `5000`
D. none of the containers can have more than `5000` atoms.

Answer

C

Explanation

Since radioactivity is a probability dependant phenomenon, nothing can be said decisicely.
