The number of combinations of 4 numbers out of 8 is 8C4= (8*7*6*5/(4*3*2*1) = 70.
In a combination, the order of the numbers does not matter so that 2345, 2454, 4523 etc are all counted as 1.

There are 120 permutations and 5 combinations.
654321-100000= 554321 combinations
2 to the 7th power = 128 * * * * * No. That is the total number of combinations, consisting of any number of elements. The number of 2 number combinations is 7*6/2 = 21
10,000 * * * * * WRONG! That is the number of permutations, NOT the number of combinations. The number of combinations denoted by nCr = n!/[r!*(n-r)!] = 10!/[4!*6!] = 10*9*8*7/(4*3*2*1) = 210
Six: 234, 243, 324, 342, 423, and 432
There are 120 permutations and 5 combinations.
Assuming you are using the standard English alphabet, the number of combinations you can make are: 26 x 26 = 676 combinations.
654321-100000= 554321 combinations
the answer is = first 2-digit number by using 48= 28,82 and in 3 digit is=282,228,822,822
2 to the 7th power = 128 * * * * * No. That is the total number of combinations, consisting of any number of elements. The number of 2 number combinations is 7*6/2 = 21
factorial six tat is 6*5*4*3*2*1=720 combinations
10,000 * * * * * WRONG! That is the number of permutations, NOT the number of combinations. The number of combinations denoted by nCr = n!/[r!*(n-r)!] = 10!/[4!*6!] = 10*9*8*7/(4*3*2*1) = 210
The number of combinations of 7 numbers from 10 is 10C7 = 10*9*8/(3*2*1) = 120
123 132 213 231 312 321
If each number can be used only once then there are just four: 2345, 2346, 2456 and 3456. There are no others because the order of the digits does not matter in combinations.
Three combinations: 23, 24 and 34
Their is 25 combinations
