Since it is clear that Sums remain a mantra to many I have posted some
analysis results here.

The first part is a frequency analysis for all possible sums. ie for a sum
of 249 it shows how many combinations (ie tickets) will produce this sum.
It will not surprise the weenies to see that it is pretty close to a Normal
distribution (bell curve or tit to the non-weenies). You will also be amazed
to see that the total permutations for all the sums adds up to the total
number of tickets.

The second (much shorter part is a sequence analysis bit. It gives counts
for combinations of sequences - starting from sequences of 6 such as
'1,2,3,4,5,6' through to non-sequences '1,3,5,7,9,11'. You will also not be
surprised to see that non-sequences amount for about half of all possible
tickets.

The point of this is that lots of intuitively unlikely events are actually
quite likely. The other point is that all of this information is not
helpful.

Picking 165,772 tickets with a sum of 150 is no better than picking an
equivalent number of tickets out ouf a hat. 150 as a sum is more likely than
any other sum simply because there are more ways of generating it, but all
tickets are equally likely.


OBTW This information is brought to you free of charge. :-)
