Bayes' Theorem
Probability that a test is correct, given the real probabilities of true and false positives and negatives
PrA_X (probability of A given X)
PrX_A (probability of X given A)
PrA (probability of A)
PrX_nA (probability of X given A is false)
PrnA (probability of A being false)

PrA_X (probability of A given X)
PrX_A (probability of X given A)
PrA (probability of A)
PrX_nA (probability of X given A is false)
PrnA (probability of A being false)
PrA_X=(PrX_A*PrA)/(PrX_A*PrA+PrX_nA*PrnA)
PrA_X=(80%*1%)/(80%*1%+9.6*99%) = 7.76
