WebNow according to Bayes’ theorem, P(A B) = P(A)P(B A) / (P(A)P(B A) + P(not A)P(B not A) ) So, if we know P(C⁺), we can easily calculate P(C⁺ +) by plugging in the values in the above equation. So, to calculate P(C⁺), you can just just divide the number of cases in your country by the total population. Web31 aug. 2015 · Figure 1. The binomial probability distribution function, given 10 tries at p = .5 (top panel), and the binomial likelihood function, given 7 successes in 10 tries (bottom panel).
