Question

How to calculate the value of P(cavity | toothache) = P(cavity ∧ toothache) / P(toothache) based on the following full joint distribution?

Answer

(0.108 + 0.012) / (0.072 + 0.008 + 0.144 + 0.576)

Answer

(0.108
+ 0.012) / (0.108 + 0.012 + 0.016 + 0.064)

Answer

(0.072 + 0.008) / (0.072 + 0.008 + 0.144 + 0.576)
