Accepted Answer

P(toothache ∧ catch | Cavity) = P(toothache | Cavity) P(catch | Cavity)

Answer

P(toothache ∧ catch | Cavity) = P(toothache ∧ catch | Cavity) P(catch | Cavity)

Answer

P(toothache ∧ catch | Cavity) = P(toothache ∧ Cavity| catch) P(catch ∧ Cavity | catch)

Answer

P(toothache ∧ catch | Cavity) = P(toothache | Cavity) ∧ P(catch | Cavity)
