What is the probability of a radioactive nucleus to survive one mean life?

In the gamma decay of a nucleus

Find the probability of survival of a radioactive nucleus for one mean life

For the decay of nucleus, the possible reason which is not true

For the decay of nucleus, the possible reason which is not true

For the decay of nucleus, the possible reason which is not true

A sample contains a large number of nuclei. The probability that a nucleus in the sample will decay after four half - lives is (a)/(b) where a and b are least positive integers. Value of a+b will be
