In the following table, a decision (Y/N) is being taken based on the four categories (i.e., Category 1, Category 2, Category 3, Category 4) which are impacting the decision.

Category 1	Category 2	Category 3	Category 4	Decision
A	P	V	I	N
A	P	V	J	N
B	P	V	I	Y
C	Q	V	I	Y
C	R	U	I	Y
C	R	U	J	N
B	R	U	J	Y
A	Q	V	I	N
A	R	U	I	Y
C	Q	U	I	Y
A	Q	U	J	Y
B	Q	V	J	Y
B	P	U	I	Y
C	Q	V	J	N

Using Bayesian Classification, find the decision related to the unseen sample K = (Category 1=A, Category 2=Q, Category 3=U, Category 4=I). Cleary state each and every step. Show all your calculations properly.
