P(1st number matching) = 1/49  (once drawn, 48 numbers remain)
P(2nd number matching) = 1/48 (once drawn, 47 numbers remain))
P(3rd number matching) = 1/47 (etc.)
P(4th number matching) = 1/46 
P(5th number matching) = 1/45 
P(6th number matching) = 1/44 

At this points the odds of winning =
 = 1/(49x48x47x46x45x44) = 1/(1.00683475x10¹⁰).

But since we can choose the 6 numbers in any order, then we have to divide (1.0068347x10¹⁰)  by 6! (factorial 6 = 6x5x4x3x2x1= 720)

(1.00683475x10¹⁰)/6! = (1.00683475x10¹⁰)/720 = 13,983,816

And the P(of getting all 6 numbers) = 1/13,983,816

What's the difference between combinations and permutations?
Stells [14]

Answer:

The difference between combinations and permutations is that in permutations, the order matters, while it doesn't with combinations. For example, if you are given 5 numbers (1,2,3,4,5) and you have to determine how many 3 digit numbers you can make, that is a permutation question because 123, 231, 321, etc. are all different  numbers. If, for example, we have to find how many ways three people can be chosen out of a group of 5, that is a combination question and you must use the combination formula as the order of the three people does not matter. Other than the order, combinations and permutations are the same
