You have 9 options for the first position (all except zero); 9 options for the second position (any digit except the digit used for the first position; 8 options for the third position; 7 options for the fourth position; 6 options for the fifth position; and 5 options for the sixth position. Multiply everything together.
To form a 4-digit number using the digits 2, 6, 9, and 5 without repeating any digit, you can use all four digits. The number of ways to arrange 4 digits is calculated as 4! (4 factorial), which equals 24. Therefore, you can form 24 different 4-digit numbers with the numerals 2695 without repeating any digit.
