How many combinations of 2 and 3 digit number using 4 and 8?
the answer is = first 2-digit number by using 48= 28,82 and in 3 digit is=282,228,822,822
How many two digit number combinations can you get using the number 1234 without repeating a digit?
There are twelve possible solutions using the rule you stated.
How many 3 digit combinations using digits 0 to 9 repeating allowed?
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.
How many 4 digit combinations using 0-9 if each number may be used more than once?
10,000 combinations.
How many number of combinations can be formed by using numbers123456 within 500?
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.
If using numbers 0 through 9 how many different 4 digit combinations can be made?
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.
What are all the possible lock 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.
How many 4 number combinations using digits 1357 one and only once?
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.
How many combinations are there for a 8 digit number 1-8?
Using the eight digits, 1 - 8 ,-- There are 40,320 eight-digit permutations.-- There is 1 eight-digit combination.
How many 3 digit combinations can be made with 12345?
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 ).
How many 4 digit combinations are there in the number 6000 using only 6 and 0?
There is only 1 combination.
