To solve the problem, we need to find the range of \( P(B \cap C) \) given the probabilities of events \( A \), \( B \), and \( C \) and their intersections. We will follow these steps: ### Step 1: Write down the known probabilities - \( P(A) = 0.6 \) - \( P(B) = 0.4 \) - \( P(A \cap B) = 0.8 \) - \( P(A \cap C) = 0.3 \) - \( P(A \cap B \cap C) = 0.2 \) ...
