The number of different groups of students that can be formed from 16 students depends on the size of the groups being formed. If you are looking for all possible combinations of groups of any size (from 1 to 16), you can use the formula for combinations. The total number of combinations would be (2^{16} - 1) (subtracting 1 to exclude the empty group), which equals 65,535 different groups. If you specify a particular group size, the calculation would be different.
20 x 19 x 18/3 x 2 = 1,140 groups

To find the number of different groups of 6 that can be formed from 9, you can use the combination formula ( C(n, r) = \frac{n!}{r!(n-r)!} ). Here, ( n = 9 ) and ( r = 6 ). Thus, ( C(9, 6) = \frac{9!}{6! \cdot 3!} = \frac{9 \times 8 \times 7}{3 \times 2 \times 1} = 84 ). Therefore, there are 84 different groups of 6 from a set of 9.

There are 27 choose 25 ways, which is equivalent to 27! / (25!(27-25)!) = 351 possible different groups of 25 people that can be formed from a total of 27 people.
20 x 19 x 18/3 x 2 = 1,140 groups
Infinitely many.
Ther are a lot of different types of cars in the world...to many to list!
There are 6 different police cars.
23 x 22 x 21 x 20/4 x 3 x 2 = 8,855 groups
There are many different ways in which pollution is created. Running cars or dumping trash are forms of harmful pollution.
there are about 5,000 to 10,000 different cars out there.
There are 6 groups.
Like 15 - 20 different cars.
