P(Yes)=3/10

P(No)=7/10

P(X\Yes) x P(Yes)=$\text{P( yes\yes) x P(Employed\yes)x P(Average\yes) x P(Yes)}\\ =0 * 2/3 * 3/3 * 3/10\\ =0$

P(X\No) x P(No)= $\text{P( yes\no) x P(Employed\no)x P(Average\no) x P(no)} \\ =\text{3/6 * 2/6 * 1/6 * 7/10} \\ =0.0194 \\ =0 \lt0.0194$

Therefore the naive Bayesian classifier predicts Defaulted= “No” for sample X
