There is an infinite number of ways three numbers can have the sum of 11
With whole numbers, there are five ways.
4,5 & 12 is one of many solutions...
There are 676,000 ways to make the license plates.
Five numbers can be arranged in 5! = 120 ways.

Six ways. Eleven if you ignore commutativity and treat 2+10 as different from 10+2.
Three ways (I think).
6 ways: 931,913,139,193,391,319
There are 22 ways.
Three ways. 3 + 37 11 + 29 17 + 23
How about: 17+7 = 24, 19+5 = 24 and 11+13 = 24 as three examples
With whole numbers, there are five ways.
The first of the three can be any one of 6 numbers. For each of these choices, the second of the three can be any one of 5 numbers. For each of these choices, the third of the three can be any one of 4 numbers. So there are (6 times 5 times 4) ways to pull three numbers out of the six available = 120 ways. If you don't care what order you wind up with ... meaning, if 1-3-5 and 5-1-3 and 3-1-5 are all the same thing as far as you're concerned ... then there are only 20 different groups of three that you can wind up with.
