(a) Assume that a particular nucleus, in a radioactive sample, has a probability `rho` of decaying in the interval t to `t+Deltat`. Taking that the nucleus actually does not decay in the above interval, what is probability that it will decay in the interval t `+Deltat` to `t+2Deltat`?
(b) Find the mean life of `.^(55)C_(0)` is its activity is known to decreases 4% per hour. `ln((25)/(24))=0.04`.
