i dont understand the question. can you do this step by step.

Beschouw de getalrepresentaties excess-128, 1's-Complement en 2's-Complement en de bitcombinaties: Consider the number representations Excess-128. I's Complement, and 2's Complement, and the sequences of eight bits: 00000000 10000000 11111111 01111111 Hoeveel van deze bitcombinaties representeren in precies een van de drie getalrepresentaties het getal 07/ How many of these sequences of bits represent the value 0 in exactly one of these three representations? a. 3 of 473 or 4 b. 2 c. 1 d. 0 Beschouw de getalrepresentaties excess-128, 1's-Complement en 2's-Complement en de bitcombinaties: Consider the number representations Excess-128.
