Well, isn't that a happy little question! The most frequent 3-digit combination is likely 123, as it follows a simple pattern and is easy to remember. But remember, every combination is special in its own way, just like every tree you paint has its own unique beauty. Just trust your instincts and let your creativity flow!
If the digit 0 is allowed then the answer is 1/(10*9*8) = 1/720 = 0.0014 approx. If 0 is disallowed, then 1/(9*8*7) = 1/504 = 0.0020 approx.
Any of the digits you did not choose are the most likely candidates
Yes, unless the 3 digit number is negative, or a decimal.
120 combinations using each digit once per combination. There are 625 combinations if you can repeat the digits.
No.
There are no 3 digit numbers between 0 and 9 because 0 and 9 are 1 digit numbers.
Yes, in a 3-digit lock combination, the digits can range from 0 to 9. This means that each digit in the combination can be any number from 0 to 9, including the digit 0. Therefore, 0s can certainly appear in 3-digit lock combinations.

There are 15180 combinations.
You should try out all of the three-digit combination. There are 10x10x10 = 1,000 possible combination (assuming digits 0-10).
In the sequence 911147835, the digits can be grouped as follows: 9, 1, 1, 1, 4, 7, 8, 3, 5. The digit '1' appears three times, while the other digits appear once. This indicates a relationship where '1' is the most frequent digit, while the others contribute to a varied numeric set. Overall, the sequence shows a combination of repetition and unique values.

The smallest 4-digit palindrome is 1001. To find if it can be expressed as the sum of two 3-digit palindromes, consider the smallest 3-digit palindromes, which are 101, 111, 121, etc. The combination of 101 and 900 (another 3-digit palindrome) gives 1001, making 1001 the sum of two 3-digit palindromes. Thus, the answer is 1001.
30.The first digit can be one of three digits {3, 6, 9} corresponding to the last digit being {1, 2, 3}, and for each of those three digits, the middle digit can be one of ten digits {0 - 9}, making 3 x 10 = 30 such numbers.It is assumed that a 3 digit number is a number in the range 100-999, excluding numbers starting with a leading zero, eg 090 is not considered a 3 digit number (though it would be a valid 3-digit number for a combination lock with 3 digits).
Start dialing. If it's a three digit lock, then you can try all the possibilities in a reasonably short time. If it's a four digit lock, then it will obviously take longer, but it's still something a diligent person can manage in an afternoon. (If you try a combination per second, which isn't that hard, you can exhaustively search out a four-digit combination in at most 3 hours.)
