8
The number of combinations of six numbers that can be made from seven numbers will depend on if you can repeat numbers. In all there are over 2,000 different numbers that can be made.
There are 8C6 = 8*7/(2*1) = 28 combinations.
There are: 7C6 = 7
137, 173, 317, 371, 713, 731 Six combinations can be made.
Using the formula n!/r!(n-r)! where n is the number of possible numbers and r is the number of numbers chosen, there are 13983816 combinations of six numbers between 1 and 49 inclusive.
The number of combinations of six numbers that can be made from seven numbers will depend on if you can repeat numbers. In all there are over 2,000 different numbers that can be made.
If the numbers are allowed to repeat, then there are six to the fourth power possible combinations, or 1296. If they are not allowed to repeat then there are only 360 combinations.
Just 1.
Six combinations: 123, 132, 213, 231, 312, 321
Assuming that the six numbers are different, the answer is 15.
There are 8C6 = 8*7/(2*1) = 28 combinations.
There are: 7C6 = 7
137, 173, 317, 371, 713, 731 Six combinations can be made.
Using the formula n!/r!(n-r)! where n is the number of possible numbers and r is the number of numbers chosen, there are 13983816 combinations of six numbers between 1 and 49 inclusive.
figure it out then tell me :)
There are 8!/[6!(8-6)!] = 8*7/2 = 28 - too many to list.
Assuming no duplication or repetition, 720
