the probability that an individual randomly selected from a particular population has a certain disease is .05. a diagnostic test correctly detects the presence of the disease 98% of the time and correctly detects the absence of the disease 99% of the time. if the test is applied twice, the two test results are independent, and both are positive, what is the (posterior) probability that the selected individual has the disease

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
