Answer 2

To calculate the total number of possible 4-digit codes using the numbers 1, 2, and 3, we can use the fundamental principle of counting. Since we have 3 choices for each digit and we are choosing 4 digits, the total number of possible codes is 3 x 3 x 3 x 3 = 81. Therefore, there are 81 possible 4-digit codes that can be formed using the numbers 1, 2, and 3.

Answer 3

Oh, dude, let me break it down for you. So, if you're using the numbers 1, 2, and 3 to create a 4-digit code, you have 3 options for each digit. That means you have 3 x 3 x 3 x 3 = 81 possible combinations. But hey, who's counting, right? Like, you do you, man.

Answer 4

Since you've only given us 3 digits to put in 4 places, we have to assume

that it's OK to use the same digit more than once in a code. So we're also

going to assume that there's no limit on repetition.

The first digit can be any one of 3. For each one . . .

The second digit can be any one of 3. For each one . . .

The third digit can be any one of 3. For each one . . .

The fourth digit can be any one of 3.

Total possibilities = 3 x 3 x 3 x 3 = 81 possible codes.

Which are:

1111, 1112, 1113, 1121, 1122, 1123, 1131, 1132, 1133, 1211, 1212, 1213, 1221, 1222, 1223, 1231, 1232, 1233, 1311, 1312, 1313, 1321, 1322, 1323, 1331, 1332, 1333, 2111, 2112, 2113, 2121, 2122, 2123, 2131, 2132, 2133, 2211, 2212, 2213, 2221, 2222, 2223, 2231, 2232, 2233, 2311, 2312, 2313, 2321, 2322, 2323, 2331, 2332, 2333, 3111, 3112, 3113, 3121, 3122, 3123, 3131, 3132, 3133, 3211, 3212, 3213, 3221, 3222, 3223, 3231, 3232, 3233, 3311, 3312, 3313, 3321, 3322, 3323, 3331, 3332, 3333
