Only 1. In a combination, the order of the numbers does not matter. So 102478 is the same combination as 104782 or 407812 etc.
There are twelve possible solutions using the rule you stated.
To find the number of 3-digit combinations using the digits 0 to 9 with repetition allowed, we consider that each digit can be any of the 10 digits (0-9). Since there are 3 positions in the combination, the total number of combinations is calculated as (10 \times 10 \times 10), which equals 1,000. Therefore, there are 1,000 possible 3-digit combinations.
10,000 combinations.
To find the number of combinations of the digits 1, 2, 3, 4, 5, and 6 that form numbers less than 500, we can consider the constraints based on the first digit. If the first digit is 1, 2, or 3, all combinations of the remaining digits can be used. If the first digit is 4, only combinations that result in a two-digit number can be formed. The total combinations can be calculated based on these conditions, but generally, you can form various 1-digit, 2-digit, and 3-digit numbers, totaling around 120 distinct combinations.
The total number of possible lock combinations depends on the number of digits and the range of each digit. For a standard 3-digit lock using numbers 0-9, there are 10 options for each digit, resulting in 1,000 possible combinations (000 to 999). If the lock has a different number of digits or uses letters, the calculation would vary accordingly. For example, a 4-digit lock would have 10,000 combinations.
Number of 7 digit combinations out of the 10 one-digit numbers = 120.
the answer is = first 2-digit number by using 48= 28,82 and in 3 digit is=282,228,822,822

To calculate the number of different 4-digit combinations that can be made using numbers 0 through 9, we use the concept of permutations. Since repetition is allowed, we use the formula for permutations with repetition, which is n^r, where n is the number of options for each digit (10 in this case) and r is the number of digits (4 in this case). Therefore, the number of different 4-digit combinations that can be made using numbers 0 through 9 is 10^4, which equals 10,000 combinations.

To calculate the number of 4-digit combinations using the digits 1, 3, 5, and 7 exactly once each, we can use the permutation formula. There are 4 choices for the first digit, 3 choices for the second digit, 2 choices for the third digit, and 1 choice for the fourth digit. Therefore, the total number of combinations is 4 x 3 x 2 x 1 = 24. So, there are 24 possible 4-digit combinations using the digits 1, 3, 5, and 7 exactly once each.
Using the eight digits, 1 - 8 ,-- There are 40,320 eight-digit permutations.-- There is 1 eight-digit combination.
To find the number of 3-digit combinations that can be made from the digits 1, 2, 3, 4, and 5, we consider that each digit can be used only once in each combination. The number of combinations is calculated using the formula for combinations: ( \binom{n}{r} ), where ( n ) is the total number of items to choose from, and ( r ) is the number of items to choose. Here, ( n = 5 ) and ( r = 3 ), so the number of combinations is ( \binom{5}{3} = 10 ).
There is only 1 combination.
