(1) Starting with the interval [0, 1, we first take away the middle third to obtain two small intervals. The one that is taken away is (1/3.,2/3) and the two remaining intervals are [0,1/3] and [2/3, 1]. Next we take away the middle third for each of the two remaining intervals to produce four even smaller intervals. Keep taking the middle third for each of the remaining intervals, and so on forever, we wil end up with a set of...
