There are multiple ways to add three numbers together to get a sum of 17. One possible combination is 5 + 6 + 6, another is 9 + 4 + 4, and yet another is 7 + 5 + 5.
Three positive integers: 120.

Three.
Three numbers can be arranged in 27 different sequences if repetition is allowed, and in 6 different sequences if it's not.
add all the numbers together and divid by how many numbers you added
Since there are infinitely many prime numbers there are infinitely many sets of three prime numbers and so there are infinitely many products.

There are infinitely many rational numbers between any two (different) numbers, no matter how close together they are.
If the numbers can be repeated and the numbers are 0-9 then there are 1000 different combinations.
