More precisely, it is defined as the probability-weighted sum of all possible values in the random variable's support, As the equation indicates, the posterior probability of having the disease given that the test was positive depends on the prior probability of the disease \( P(\text{Disease}) \). This number is always between 0 and 1, where 0 indicates impossibility and 1 indicates certainty. More precisely, it is defined as the probability-weighted sum of all possible values in the random variable's support, At the core of Bayesian statistics is the idea that prior beliefs should be updated as new data is acquired.
