It looks like you are asking how many combinations of 6 numbers are there in the 28 numbers 1 through 28. This is known as the number of combinations of 28 things taken 6 at a time. The answer is 28!/(6!22!) (n! means n factorial, which is the product of all the integers from 1 to n). I get 376,740 if I haven't made an error in arithmetic.
There are an infinite number of possibilities, including fractions, and sets where two of the three numbers are negative. For positive integers, the sets are: 1, 1, 56 1, 2, 28 1, 4, 14 1, 7, 8 2, 2, 14 2, 4, 7
5They are 1,2,4,7,14, and 28
Prob(two sets of matched birthdays) = 1 - [Prob(No matched birthdays)] + [Prob(One set of matched birthdays)] = 0.63
There are approx 5.709*10^45 possible sets of numbers that can be made out of the composite numbers in 1 and 200.
9 with 1 remaining 28 - 1 = 27 = 3 x 9
There are 376740 such sets and you must think me crazy if you think I will list them all!

There are 28C6 = (28*27*26*25*24*23)/(6*5*4*3*2*1) = 376,740 sets.
