Half-life of a radio active substance ' \(A\) ' is 4 days. The probability that a nucleus will decay in two half-lives is
Solution:
After two half lives \(\frac{1}{4}\) th fraction of nuclei will remain undecayed. Or, \(\frac{3}{4}\) th fraction will decay. Hence, the probability that a nucleus decays in two half lives is \(\frac{3}{4}\).
