To find the number of combinations of 3 numbers from a set of 5 numbers, you can use the combination formula ( C(n, k) = \frac{n!}{k!(n-k)!} ). Here, ( n = 5 ) and ( k = 3 ). Plugging in the values, we get ( C(5, 3) = \frac{5!}{3!(5-3)!} = \frac{5 \times 4}{2 \times 1} = 10 ). Therefore, there are 10 combinations of 3 numbers from a set of 5 numbers.
100=2*2*5*5 so only 1 combination of 3 nos. r der
Just the one. The order of the numbers does not matter in a combination so that 123456 is the same combination as 245136.
120 WRONG! That is the number of PERMUTATIONS. In the case of combinations, the order of the numbers does not matter, so there is only 1 5-number combination from 5 numbers.
This question does not make sense since a combination is independent of the order of its elements. That is, the combinations 1245 and 5142 are the same. Consequently, there can be no "last " numbers in a combination.

Number of combinations = 59*58*57*56*55/(5*4*3*2*1) = 5006386.

5*4*3*2*1 = 120 combinations. * * * * * No. The previous answerer has confused permutations and combinations. There are only 25 = 32 combinations including the null combinations. There is 1 combination of all 5 numbers There are 5 combinations of 4 numbers out of 5 There are 10 combinations of 3 numbers out of 5 There are 10 combinations of 2 numbers out of 5 There are 5 combinations of 1 numbers out of 5 There is 1 combination of no 5 numbers 32 in all, or 31 if you want to disallow the null combination.
about... 25 just take 5 numbers times 5 numbers
None. 3 digit numbers are not divisible by 19 digit numbers.
There are 5*5*5 = 125 such numbers.
5 + 8 + 2 = 15. 15 / 3 = 5 All you have to do is add the numbers, then divide the answer by how many numbers you added.
There are 232 numbers between 1 and 500 that are divisible by 3 or 5.
