📊 Probability Tree Visualizer

// dua event berurutan dengan conditional probabilities

P(A) = 0.30

P(B | A) = 0.80

P(B | not A) = 0.20

JOINT PROBABILITIES

P(A ∩ B):-

P(A ∩ not B):-

P(not A ∩ B):-

P(not A ∩ not B):-

MARGINAL & POSTERIOR

P(B) marginal:-

P(not B):-

P(A | B) Bayes:-

Total cek:1.000

Coba: Set P(A)=0.01 (rare disease), P(B|A)=0.99 (sensitivity test), P(B|not A)=0.05 (false positive). Lihat P(A|B) = posterior. Bayes paradox: tes hampir sempurna tapi P(disease | positive) rendah karena prior rendah.
