Let E and F be events with `P (E) =3/5`, `P (F) =3/(10)`and `P(EnnF)=1/5`. Are E and F independent?

Text Solution

AI Generated Solution

To determine whether the events E and F are independent, we will use the definition of independence for two events. Two events E and F are said to be independent if: \[ P(E \cap F) = P(E) \cdot P(F) \] Given: - \( P(E) = \frac{3}{5} \) - \( P(F) = \frac{3}{10} \) - \( P(E \cap F) = \frac{1}{5} \) ...
