Answer:
13,983,816 or thirteen million-nine-hundred-and-eighty-three-thousand-eight-hundred-and-sixteen. You can work this out by : please look below ( this is some complex maths so only look if your good at maths. A calculator would also help.)
(6/49)*(5/48)*(4/47)*(3/46)*(2/45)*(1/44)
multiply this by "n" ( "n" equaling the amount of combinations) and if you get 1 "n" is correct for that number but only for that number so work out the above divisions and multiplications and you should arrive at :0.000000071 and then multiply by 13,983,816.
