Where is the number of elements of every group and i goes from 1 to k.

Now, there are 100 kids in the camp and we need to assign them into 4 different activities and at most 35 kids can do archery, 20 can do hiking, 25 can do crafts and 20 can do swimming. So,  it means that n is equal to 100, k is equal to 4, is 35, is 20, is 20 and is 25.

Finally, replacing values, we get:

So, There are ways to assign the kids to the 4 activities.
