Question

Which conditions must hold for \[B_1, B_2, \dots, B_n\] in Bayes' Theorem?

Options

• They must be observed after event \[A\].

• They must all have probability zero.

• They must be dependent and incomplete events.

• They must be mutually exclusive and exhaustive events.

Answer 1

The events \[B_1, B_2, \dots, B_n\] must divide all possible cases without overlap. Therefore, they are mutually exclusive and exhaustive events.
