The correct Answer is:
To solve the problem, we need to find \( P(A \cap B') \), where \( B' \) is the complement of event \( B \). Given that events \( A \) and \( B \) are independent, we can use the properties of independent events to find the required probability. ### Step-by-Step Solution: 1. **Identify the Given Probabilities**: - \( P(A) = 0.6 \) - \( P(B) = 0.7 \) 2. **Calculate the Probability of the Complement of B**: - The probability of the complement of event \( B \) is given by: \[ P(B') = 1 - P(B) = 1 - 0.7 = 0.3 \] 3. **Use the Independence of Events A and B**: - Since \( A \) and \( B \) are independent, the probability of the intersection of \( A \) and \( B' \) can be calculated as: \[ P(A \cap B') = P(A) \cdot P(B') \] 4. **Substitute the Known Values**: - Now substitute the values we have: \[ P(A \cap B') = P(A) \cdot P(B') = 0.6 \cdot 0.3 \] 5. **Calculate the Final Probability**: - Performing the multiplication gives: \[ P(A \cap B') = 0.6 \cdot 0.3 = 0.18 \] Thus, the final answer is: \[ P(A \cap B') = 0.18 \]
