    1. Find \(\mathrm { P } ( B )\)
    2. Determine whether or not \(A\) and \(B\) are independent.
    Given that \(\mathrm { P } ( C \mid B ) = \mathrm { P } ( C )\)
  2. find the value of \(p\) and the value of \(q\) The event \(D\) is such that
    • \(\quad A\) and \(D\) are mutually exclusive
    • \(\mathrm { P } ( B \cap D ) > 0\)
    • On the Venn diagram show a possible position for the event \(D\)
