Assuming each of the given digits can be used only once, the answer is 24. If not, the answer is infinity.
4 x 3 x 2 ie 24
2578 5287 5782 8572
24 of them.
I take it that you want to make three digits numbers with 8,7,3, and 6 without repetition. The first digit cane be selected from among 4 digits, the second from 3 digits, the third digit from 2, hence the number of three digit numbers that can be formed without repetition is 4 x 3 x 2 = 24
if using all four digits each time, 24.
24 different numbers.
Using the combination C(4,3) I got the answer 24. Its either a combination or a permutation.
If you want 4-digit numbers, there are 24 of them.
If the digits can repeat, then there are 256 possible combinations. If they can't repeat, then there are 24 possibilities.
To write 24 January 2014 in 5 letters without using numbers kindly write 24.1.14.
If you have 24 distinct characters, then there are 2,704,156 combinations of 12 characters. Normally there are only ten digits and so 24 of them would contain duplicates. In that case the answer will depend on the duplication.
One way is: 3*89-8 = 24
No. You cannot form 24 using only 1 tile, for example.
By using: (3*6)+(3*2) = 24
72 reverse the digits divide by 3 = 24
Without repeating any of the digits: 4*3*2*1 = 24 If repeated digits are allowed, then 4*4*4*4 = 256
With repeated digits, 43 = 64 Without repeated digits, 4*3*2 = 24
24 - without using a calculator !
If the digits may be repeated, there are four choices for the first digit, four choices for the second, and four choices for the third. Thus there are 4x4x4 = 64 possible three-digit numbers with those digits. If the digits may not be repeated, there are still four choices for the first digit, but then only three remaining choices for the second, and then just two choices for the third. In this case there are only 4x3x2 = 24 possibilities.
