# splunge
if it's 49 numbers then its
49 x 48 x 47 x 46 x 45 x 44
which = 10,068,347,520 this is for all 6 numbers of course

if not then replace the 49 with the max number and follow same pattern :-p

# It has something to do with the binomial expansion, methinks..
I worked it out in maths before..
*Gets textbook out*
"The number of ways of choosing r items from a group of n items is written nCr and is calculated by:

n!/(n-r)!r!

r = 6
n = 49

So nCr = 13,983,816

And that concludes today's A-Level Maths lesson.

# I think they are
But it's about 14 million to actually win anything - even if it's only a tenner.
