Their is nothing in the picture, it’s all black
Each question has three possible distinct answers.
Ten questions have 3^10 possible distinct answers sheets.
=>
(3^10)+3 will guarantee that at least 3 answer sheets are identical.
Numerically,
(3^10)+3 = 59049 +3 = 59052
(2, -1), (6,- 4), and (6, -1). Hope this helps man!
