(a) By applying Laplace Smoothing with Laplace-k estimate k=2, calculate the following: -
P(Y=1) = ?
P(X1=A|Y=1) = ?
P(X1=A|Y=0) = ?
P(X2=S|Y=1) = ?
P(X2=M[Y=0) = ?
P(Y=0) = ?
P(X1=B|Y=1) = ? P(X1=C|Y=1) =?
P(X1=B|Y=0) = ? P(X1=C[Y=0) = ?
P(X2=M|Y=1) = ? P(X2=L[Y=1) =?
P(X2=L[Y=0) = ?e
P(X1=D[Y=1) = ?«
P(X1=D|Y=0) = ?«
P(X2=S|Y=0) = ?H
