Question

Which conditions are specified for the probabilities in Bayes' Theorem?

Options

• \[P(B_i)=0\] and \[P(A)=0\]

• \[P(B_i)=1\] and \[P(A)=1\]

• \[P(B_i)>0\] and \[P(A)>0\]

• \[P(B_i)<0\] and \[P(A)>1\]

Answer 1

The denominator and conditional probability must be well-defined. Hence the theorem requires \[P(B_i)>0\] and \[P(A)>0\].
