Imagine the following scenario involving marbles as "radioactive isotopes". Let's say the half-life of green marbles is 1 million years.

In one hand, you're holding 2 green marbles. In your other hand, you're holding 500,000 green marbles.

Hypothetically, noting that we have two different starting amounts of "isotopes", how long will it take for half of each amount to decay?
