Question

If E and F are independent, which pair is also independent?

Options

• E and F only when \[P(F)=0\]

• E' and F'

• E' and F' only when they are mutually exclusive

• E and F only when \[P(E)=0\]

Answer 1

If E and F are independent, then E' and F' are also independent. Therefore, all the related complement pairs preserve independence.
