'During the coronavirus disease 2019 (COVID19) crisis, there has been public outcry for mass screening of the population in hopes to control an actively unfolding event. To this date, there is one est that has assisted in the current crisis, real-time reverse transcriptase polymerase chain reaction (rRT-PCR). Although becoming more readily available, there are short comings to the test when placed in real world situations. The probability that the rRT-PCR correctly identi?es someone with COVID as positive is 0.87, and the probability that the test incorrectly identifies someone without COVID as positive is 0.01. The incidence of the COVID in the general population is 0.001. You take the test, and the result is positive. Let P denote the event that you have COVID. Let R denote the event that the rRT-PCR result is positive. What is the is the equivalent mathematical notation for 0.87? What is the is the equivalent mathematical notation for 0.01?
