A radioactive sample A decays to form B.(A→ B). The half life of A i – InterviewSolution

1.	A radioactive sample A decays to form B.(A→ B). The half life of A is t12=8 years. Only A is present at t=0. Find the time at which if we are able to pick one atom out of the sample, then probability of getting B is 15 times of getting A.
Answer» A radioactive sample $A$ decays to form $B$ . $(A \to B)$ . The half life of $A$ is $t_{\frac{1}{2}} = 8 years$ . Only $A$ is present at $t = 0$ . Find the time at which if we are able to pick one atom out of the sample, then probability of getting $B$ is $15$ times of getting $A$ .
