Question

Using the universal set U={1,2,3…10}, find the set specified by each of these bit strings (i)1111001111 , (ii)0101111000 and (iii)1000000001

Answer 1

Each bit string is 10 digits long so we can relate each bit position to a number between 1 and 10.

(i) {1,2,3,4,7,8,9,10}

(ii) {2,4,5,6,7}

(iii) {1,10}

These are all subsets of U.
