Suppose that 0.5% of all people have a disease. There is testing available for this disease. If the person being tested has the disease, the test will always return positive. However, if the person being tested does not have the disease, the test will return negative 98% of the time and return positive the rest of the time. If I randomly choose a person and they test positive, what is the probability that they actually have the disease? Express your answer as a common fraction.

the answer is 31.27mph

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
