But the order isn't significant
It is if you're betting on a specific order they come out of the barrel which is what Graham says here
Right...For 1,2,3,4,5,6 in that order:
For the lottery though they don't keep the order...

m_f... but order is significant as you said...
odds of the balls being drawn 1, 2, 3, 4, 5 and then 6 in that order
Therefore, the first ball drawn has to be a 1, giving odds of 1/49.
If order wasn't important, as in the normal lottery draw, then that first ball can be any number from 1 to 6, giving odds of 6/49.

There is no more or less reason why any sequence of number will be drawn over another random series of numbers.
One sequence (1,2,3,4,5,6) is not more or less likely than another sequence (1,6,2,5,3,4). Correct.
BUT that's not what you are asking about.
You are trying to compare the probability of drawing one particular sequence (1,2,3,4,5,6 in order) versus drawing any one of the 720 unordered variations of that sequence.
Just think about that first ball: in an order sequence it MUST be 1 otherwise you fail, so the odds of the first ball being right are 1 out of 49. For the unordered sequence the first ball can be 1,2,3,4,5 or 6 and we are still on a winner, so the odds that the first ball being right are 6/49.

All this (possibly, although I don't care if its true it's fun to speculate) proves that Posh is not very liberal with the goodies here is why:
going back to the biology a minute, the sex is determined by the sperm gamete a male either gives an x sperm or a y sperm.
So this is also interesting:
Studies indicate that the sperm with the X chromosome - or female chromosome - have a longer life span than the male sperm (with the Y chromosome).
Yet the male sperm appear to have a higher motility. Sperm motility is measured in two ways: percentage of sperm exhibiting movement, and the quality - or dynamics - of this movement, which is called the forward progression. Poor motility means the sperm have a difficult time swimming toward the egg. FertilAid for Men is a non-prescription male fertility supplement that has been shown to improve sperm motility.
Hence, "female sperm" exhibit less motility - yet have a longer life span. The "male sperm" exhibit increased motility, but have a shorter life span than the X chromosome sperm.
It is believed that if intercourse takes place closer to ovulation, then the probability is greater that the child will be male, due to the high motility (forward progression) and the decreased life span of the sperm.
This has been socially analysed by some commentators that if you have mostly boys then you likely only have sex when she says its OK, if you have mainly girls you are more likely to have regular sex and not care about when she ovulates.
I have two girls.........

Apparently, Jews are more likely to have sons, because of the cleanliness laws dictating when during a woman's cycle they can have sex.
We have an office-theory that fathers using computers a lot increases the chance of having a daughter. Three of us have had 5 daughters between us and no boys.

I sit behind a desk all day and have one of each. Perhaps I walk to the brew machine more often than most.
