The Venn diagram below shows events \(A\) and \(B\), where \(P(A) = 0.3\), \(P(A \cup B) = 0.6\) and \(P(A \cap B) = 0.1\).

The values \(m\), \(n\), \(p\) and \(q\) are probabilities.

image essential to understanding the question
    1. Write down the value of \(n\).
    2. Find the value of \(m\), \(p\) and \(q\).
  2. Find \(P(B)\).
