You can select 12 numbers for the first digit, 11 numbers for the second digit, and 10 numbers for the third digit; so 12*11*10 = 1320 sets of 3 numbers can be made out of 12 different numbers.
6 if order doesn't matter
There are approx 5.709*10^45 possible sets of numbers that can be made out of the composite numbers in 1 and 200.
there are 5 diffeerent sets Natural Numbers whole numbers integers rational numbers irrational numbers.

Since there are infinitely many prime numbers there are infinitely many sets of three prime numbers and so there are infinitely many products.
If you mean how many different sets of 7 can be made from 9 numbers, the answer is (9 x 8)/2 ie 36.
yes!

Three sets
15504 different sets of 5 numbers in each. This is a combination of 5 from 20: 20C5 = 20!/(20-5)!5! = 20x19x18x17x16/5x4x3x2x1 = 15504.
The theory of numbers is based on the property of sets of different kinds of numbers.
There are eight sets of 3 consecutive numbers in 12 hours.
