Answer:
I think your question is missing something,i tried to explain you by examples.
Explanation:
1)
n = 37, k = 6.
Thus, the answer is (37 + 6 − 1)C6-1 = 42C5
=> C(42,5) = 850668
Where C(n,r) is the combination
2)
n = 37
Since xi >= 2 that means x1 >= 2 , x2 >= 2, x3 >= 2 , x4 >= 2, x5 >= 2, x6 >= 2
Then, we distribute the remaining 37 − 2 − 2 − 2 − 2 − 2 - 2 = 25
Thus, the answer is (25 + 6 − 1)C6-1 = 30C5
=> C(30,5) = 142506
