hi
in the attachment is the question
I have problem solving it
from question I just knew the Prior Probability for that their claim correct is =0.2 and not correct =0.8
after he did the experiment he found that it is correct 100 %
but I could not find where is the posterior![]()
Prior Probability =0.2
correcting information= 1
posterior =?
until now this is what I came up with
thank you in advance
