    0.35
    A 0.26 Correct Answer Incorrect Answer
    B 0.25 Correct Answer Incorrect Answer
    C 0.28 Correct Answer Incorrect Answer
    D 0.24 Correct Answer Incorrect Answer

    Solution

    Given: P(B) = 0.8 and P(AǀB) = 0.35 We know that by definition of conditional probability, => P(AǀB) = [P(A∩B)]/P(B) Now by substituting the values we get, => P(A∩B) = 0.35 ×  0.8 = 0.28
