MCQ (Single Correct Answer)

Let $${E^c}$$ denote the complement of an event $$E.$$ Let $$E, F, G$$ be pairwise independent events with $$P\left( G \right) > 0$$ and $$P\left( {E \cap F \cap G} \right) = 0.$$ Then $$P\left( {{E^c} \cap {F^c}|G} \right)$$ equals

$$P\left( {{E^c}} \right) + P\left( {{F^c}} \right)$$

$$P\left( {{E^c}} \right) - P\left( {{F^c}} \right)$$

$$P\left( {{E^c}} \right) - P\left( F \right)$$

$$P\left( E \right) - P\left( {{F^c}} \right)$$
