Since 10 is a 2-digit number, it is necessary to find the numbers of combinations containing it and not containing it separately.
There are 456 combinations containing 10 and 381 not containing it, making 837 in all.
Yuo can make only one combination of 30 digits using 30 digits.
9,999,876 is the greatest seven-digit number using four different digits.
Using the combination C(4,3) I got the answer 24. Its either a combination or a permutation.
The greatest 9-digit number using three different digits is 999888777, formed by using the digits 9, 8, and 7 in descending order. The smallest 9-digit number using three different digits is 100000000, created with the digits 1, 0, and 0. This arrangement ensures that the number starts with 1, followed by the zeros to maintain the smallest value.
The order of the digits in a combination does not matter. So 123 is the same as 132 or 312 etc. There are 10 combinations using just one of the digits (3 times). There are 90 combinations using 2 digits (1 once and 1 twice). There are 120 combinations using three different digit. 220 in all.
Oh, dude, you're hitting me with some math vibes here. So, if you have 6 digits to choose from to make a 4-digit combination, you can calculate that by using the formula for permutations: 6P4, which equals 360. So, like, you can make 360 different 4-digit combinations from those 6 digits. Math is wild, man.
The smallest even number using this combination of digits is 2568.
If the digits are all different then 18. Otherwise, 192.
