48. About 0.01% of men with no known risk behavior are infected with HIV. The false negative rate for the standard HIV test 0.01% and the false positive rate is also 0.01%. If a randomly selected man with no known risk behavior tests positive for HIV, what is the probability that he is actually infected with HIV

The probability that he is actually infected with HIV given that the man selected with no known risk behavior tests positive for HIV is 0.9999.

Step-by-step explanation:

Denote the events as follows:

X = a man with no known risk behavior is infected with HIV

Y = the test is positive

The information provided is:

P (X) = 0.0001

P (Y'|X) = 0.0001

P (Y'|X') = 0.0001

Compute the probability that he is actually infected with HIV given that the man selected with no known risk behavior tests positive for HIV as follows:

Thus, the probability that he is actually infected with HIV given that the man selected with no known risk behavior tests positive for HIV is 0.9999.

what are the statements

step-by-step explanation:

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
