Physics is really modern
What is the probability of decay of a nucleus in time ?
Use the value of decay constant for the nucleus is 1 per second and time is 1 second.
Use .
The answer is 0.632.

probability of survival = N / N ( 0 ) = e − λ ∗ t .. therefore, probability of decay = 1 - ( probability of survival). where, N = number of nuclei left after time 't' N(0) = initial number of nuclei. and l a m b d a : is the decay constant. 't' is time. after this, putting the respective values gives the answer.
