Exam-Style Question on Probability
A mathematics exam-style question with a worked solution that can be revealed gradually
Question id: 354. This question is similar to one that appeared on an IB Standard paper in 2018. The use of a calculator is allowed.
Two events A and B are such that \(P(A) = 0.57\) and \(P (A \cap B) = 0.21\).
(a) Find \(P (A \cap B' ) \).
(b) Given that \(P((A \cup B)') = 0.17 \), find \(P(A|B')\).
