If you don't use any digit more than once, there are 83 combinations: 418 417 412 419 410 413 416 487 482 489 480 483 486 472 479 470 473 476 429 420 423 426 490 493 496 403 406 436 187 182 189 180 183 186 172 179 170 173 176 129 120 123 126 190 193 196 103 106 136 872 879 870 873 876 829 820 823 826 890 893 896 803 806 836 729 720 723 726 790 793 796 703 706 736 290 293 296 203 206 236 903 906 and 936
To find the number of three-digit combinations, we consider the digits from 000 to 999. Each digit can range from 0 to 9, giving us 10 options for each of the three digits. Therefore, the total number of three-digit combinations is (10 \times 10 \times 10 = 1,000).
A three digit number is any counting number between 100 and 999 (inclusive). It is made up of three digits, the first of which cannot be 0.

6*7*7 = 294
To form a three-digit number using the digits 0-9, the first digit cannot be 0 (as it would not be a three-digit number). Thus, the first digit can be any of the digits from 1 to 9 (9 options). The second and third digits can each be any digit from 0 to 9 (10 options each). Therefore, the total number of three-digit numbers is (9 \times 10 \times 10 = 900).
Six combinations if you use each digit only once per combination: 157 175 517 571 715 and 751.
To find the number of three-digit combinations, we consider the digits from 000 to 999. Each digit can range from 0 to 9, giving us 10 options for each of the three digits. Therefore, the total number of three-digit combinations is (10 \times 10 \times 10 = 1,000).
A three digit number is any counting number between 100 and 999 (inclusive). It is made up of three digits, the first of which cannot be 0.
24 three digit numbers if repetition of digits is not allowed. 4P3 = 24.If repetition of digits is allowed then we have:For 3 repetitions, 4 three digit numbers.For 2 repetitions, 36 three digit numbers.So we have a total of 64 three digit numbers if repetition of digits is allowed.

Oh, what a lovely question! If we have a three-digit code number beginning with a 7, we have 10 options for each digit (0-9). So, we have 10 choices for the first digit, 10 choices for the second digit, and 10 choices for the third digit. Multiplying these together gives us a total of 10 x 10 x 10 = 1,000 possible codes that can be made. Isn't that just delightful?
There are two choices for the first digit ... 1 or 2. For each of those . . .The second digit can be any one of the three choices. For each of those . . .The third digit can be any one of the three choices. For each of those . . .The fourth digit can be any one of the three choices. For each of those . . .The fifth digit can be any one of the three choices.The total number of possibilities is (2 x 3 x 3 x 3 x 3) = 162
