1 Two ordinary fair dice, one red and the other blue, are thrown.
Event \(A\) is 'the score on the red die is divisible by 3 '.
Event \(B\) is 'the sum of the two scores is at least 9 '.
- Find \(\mathrm { P } ( A \cap B )\).
- Hence determine whether or not the events \(A\) and \(B\) are independent.
