the probability that he carries HIV = .2582
Solution :
Probability :
Probability is a measure of the likelihood of an event occurring. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.
Probability Definition in Math
Probability can range in from 0 to 1, where 0 means the event to be an impossible one and 1 indicates a certain event. Probability for Class 10 is an important topic for the students which explains all the basic concepts of this topic. The probability of all the events in a sample space adds up to 1.
HIV in Swaziland: Swaziland has the highest HIV prevalence in the world: 25.9% of this country's population is infected with HIV
HIV positive parameter : 25.9 %
HIV negative parameter: 74.1%
HIV positive accuracies in 25.9% : 99.7 %
HIV-positive accuracies in 25.9% in error :0 .003%
If an individual from Swaziland has tested positive, the probability that he carries HIV
HIV positive accuracies in 25.9% : 99.7 %
= 99.7*25.9 /10000= .2582
the probability that he carries HIV = .2582
