Just one possibility.... 1001
There are 6 numbers between 1 and 70 that are divisible by 11. These numbers are: 11; 22; 33; 44; 55; 66.
119
There are 90 such numbers.
14
There are many possible answers. 10,11,11,17,18 is one such set.
The number of different three letter arrangements that can be done from theletters in the word "mathematics"is; 11P3 =11!/(11-3)! =990
The only possible pair of different positive numbers is (1, 11).
There are infinitely many possible answers. One such is {9, 10, 11, 13, 14, 15}.There are infinitely many possible answers. One such is {9, 10, 11, 13, 14, 15}.There are infinitely many possible answers. One such is {9, 10, 11, 13, 14, 15}.There are infinitely many possible answers. One such is {9, 10, 11, 13, 14, 15}.

11!/(3!3!2!2!) = 39916800/144 = 277200
It is not possible to answer the question without knowing anything about the set of numbers that they are pulled from.
