The answer gonna be: 1/2^n = 1/2^4 = 0.0625

So, 6.25% sample has not decayed yet!!!

The amount of the radioactive sample which has not decayed given the data is 6.25%

Assumption

Let the original amount be 100%

How to determine the amount remaining

  • Original amount (N₀) = 100%
  • Number of half-lives (n) = 4
  • Amount remaining (N) =?

N = N₀ / 2ⁿ

N = 100 / 2⁴

N = 100 / 16

N = 6.25%

Thus, 6.25% of the radioactive sample has not decayed
