5b. Suppose the universal set is ξ={0,1,2,3,4,5,6,7,8}.i. Write in enumerated form the set that is represented by the bit string 011011001 .ii. If A is represented y the bit string 110101110 and B is represented by the bit string 101011000, write the sets AUB and A as bit strings.
Q. 5b. Suppose the universal set is ξ={0,1,2,3,4,5,6,7,8}.i. Write in enumerated form the set that is represented by the bit string 011011001 .ii. If A is represented y the bit string 110101110 and B is represented by the bit string 101011000, write the sets AUB and A as bit strings.
Convert to Set: To solve the first part of the problem, we need to convert the bit string 011011001 into a set by matching each bit to the corresponding element in the universal set xi={0,1,2,3,4,5,6,7,8}. A '1' in the bit string means the element is included in the set, while a '0' means it is not included.
Enumerate Set: Enumerate the set represented by the bit string 011011001. Starting from the left, the first bit is 0, so 0 is not included. The second bit is 1, so 1 is included, and so on. The resulting set is \{1,2,4,5,7\}.
Find Union: To solve the second part of the problem, we need to find the union of sets A and B, represented by their respective bit strings. The union of two sets includes all elements that are in either set. In terms of bit strings, we perform a logical OR operation on each pair of corresponding bits.
Perform OR Operation: Perform the logical OR operation on the bit strings for A (110101110) and B (101011000). The result is 111111110, as each pair of bits has at least one '1' except for the last pair.
Resulting Set: The set A∪B represented by the bit string 111111110 is \{0,1,2,3,4,5,6,7\}, as all bits except the last one are '1'.
Given Set: The set A is already given by the bit string 110101110, so no further calculation is needed for this part.
