helder_edwin · Answer

i think it is Bayes theorem

helder_edwin · Answer

or perhaps a binomial distribution

helder_edwin · Answer

i am not sure but i think it is: p=3%  q=97%
$$ \large \binom{8}{1}p^1q^{8-1} $$

does it make sense with what u might be doing in your course?

anonymous · Answer

bayes theory would be more probable but i think it is conditional property

helder_edwin · Answer

if u compute what i wrote u get 19.39% of probability of rejecting the batch

anonymous · Answer

probability cannot equal more than 1

helder_edwin · Answer

yes 19.39%=0.1939

anonymous · Answer

not in my solution set

helder_edwin · Answer

then try bayes
