Final answer:
In the game of Sudoku, the probability that a number in a certain square is greater than 0 is 100% because the only allowable numbers are 1 through 9, and all of these are greater than 0.
Step-by-step explanation:
The question at hand pertains to the game of Sudoku and the probability of a number in a certain square being greater than 0. In standard Sudoku, which consists of a 9x9 grid, each cell will contain a digit from 1 to 9. Since the rules of Sudoku prohibit the use of the digit 0 in any cell, the probability that a given cell contains a number greater than 0 is actually 1, or 100%. This is because the only valid entries for a Sudoku cell are the digits 1 through 9, each of which is greater than 0.
Solving puzzles, such as Sudoku, can enhance one's problem-solving abilities. While there are different levels of difficulty in Sudoku, the probability question asked here is quite simple and doesn't change with the complexity of the puzzle.
