in a given numbers series 01 to 49, how many series of 6 numbers can be formed???with illustrations

Question

Given numbers 01 to 49, make unique series of 6 numbers....I e if we select 5,11,19,22,31,49/1,9,16,29,33,44 then they shd be found there.....

Answer 1

Each of 49 numbers is unique. The number of different combinations of 6 chosen at a time is ₄₉C₆ = 13,983,816.

 

That's how many distinct subsets there are. For any given subset (combination), there are then 6! = 720 orders in which they may be placed; if, however, the six are presented in ascending order, then that's just one possibility (of the particular combination of six).
