  1. State any pair of mutually exclusive events from \(A\), \(B\), \(C\) and \(D\) The events \(B\) and \(C\) are independent.
  2. Find the value of \(p\)
  3. Find the greatest possible value of \(\mathrm { P } \left( A \mid B ^ { \prime } \right)\) Given that \(\mathrm { P } \left( B \mid A ^ { \prime } \right) = 0.5\)
  4. find the value of \(q\) and the value of \(r\)
  5. Find \(\mathrm { P } \left( [ A \cup B ] ^ { \prime } \cap C \right)\)
  6. Use set notation to write an expression for the event with probability \(p\)
