6! = 720
6
Allowing numbers that start with zero, the answer is 6!/(2!*2!) = 720/(2*2) = 180
The answer is 6P5 = 6!/(6-5)! = 6*5*4*3*2*1/1 = 720
If you can repeat the numbers, it will be 6*6*6=216. If you can't, it will be 6*5*4=120.
64
You can make 4*3*2/2 = 12 numbers.
720 6 digit numbers can be made with the number 888995.* * * * *No.720 numbers would have been the correct answer IF all 6 digits were different. But they are not. There is one triplet (so divided by 3! and one pair so divide by 2!The correct answer is therefore 6!/(3!*2!) = 720/(6*2) = 60
1,956 different numbers can be made from 6 digits. You can calculate this by using the permutation function in a summation function, like this: Σ6k=1 6Pk = 6P1+6P2+...+6P5+6P6 What this does is calculate how many 1 digit numbers you can make from 6 digits, then how many 2 digit numbers can be made from 6 digits and adds the amounts together, then calculates how many 3 digit numbers can be made and adds that on as well etc.
2: the counting numbers 2 and 6.
Just the one. The order of the numbers does not matter in a combination so that 123456 is the same combination as 245136.
