Baye's theorem certain test for cholera gives 5% false positives, and 12% false negatives. If the test gives correct results 93% of the time, what percentage of people have cholera? Note: The probability of a false positive is P(you don't have cholera | the test says you do). The probability of a false negative is P(you do have cholera | the test says you do not).

The percentage of people having cholera is 89.19%.

Step-by-step explanation:

According to the Bayes' theorem the total probability of A is:

Let X = a person has chorea and Y = the test is positive.

Given:

The value of is:

Compute the value of P (X) as follows:

The percentage of people suffering form cholera is, 0.8919 × 100 = 89.19%.

Thus, the percentage of people having cholera is 89.19%.

f(x)=4
