R be two integers such that n > p > r > 0.
To prove that (n + p) choose r is equal to (n choose r) + (p choose r), we can use the definition of combinations.
According to the definition, (n choose r) represents the number of ways to choose r objects from a set of n objects, and (p choose r) represents the number of ways to choose r objects from a set of p objects.
Now, let's consider (n + p) choose r. This represents the number of ways to choose r objects from a set of (n + p) objects.
To count the number of ways to choose r objects from a set of (n + p) objects, we can divide the objects into two groups: n objects and p objects.
There are two cases to consider:
Case 1: We choose r objects only from the n objects group.
In this case, the number of ways to choose r objects from the n objects group is (n choose r), as we discussed earlier.
Case 2: We choose r objects only from the p objects group.
In this case, the number of ways to choose r objects from the p objects group is (p choose r).
Since these two cases are mutually exclusive (we cannot choose r objects from both groups simultaneously), we can add the number of ways from each case to get the total number of ways to choose r objects from the set of (n + p) objects.
Therefore, (n + p) choose r = (n choose r) + (p choose r).
This completes the proof.

Therefore, (n + p) choose r = (n choose r) + (p choose r).
This completes the proof.
