I need to find the statistical error in a counting experiment. Specifically, a decay can proceed via option A or option B and I need to find the branching ratio BR_a=(N_a)/(N_a+N_b). If I were to do this counting experiment multiple times my results for BR_a would follow the binomial distribution since there are two decay channels.(adsbygoogle = window.adsbygoogle || []).push({});

How do I quantify the statistical error in my result given that I conduct the experiment only once?
