Two dice are thrown and the sum of the number which come up on the dice is noted. Let us consider the following events associated with the experiment A: 'the sum is even'. B: 'the sum is a multiple of 3'. C: 'the sum is less than 4'. D: 'the sum is greater than 11'. Which pairs of these events are mutually exclusive?
