thank you
]]>I can solve for a specific case using generating functions and if you are up to it you can start there. You may not solve the problem but you will pick up a lot of useful mathematics.
]]>Thank you
]]>It looks like it is possible to count them but a formula for it is going to depend on what you want.
]]>thank you for your help
]]>(2+4) and (5+1)
Does order of the others count?
Are (4+2) and (1+5) solutions too?
]]>just I know X is never greater than summation of all members of the set.
]]>And you want greater than or equal to x?
]]>For the set {1,1,1,1} there is only one way to get 3, 1+1+1 = 3 and one way to get 4, 1+1+1+1 = 4. That is two ways. How do you get 4 ways?
