For several months now I have listened to the Natioinal Lottery results on a Sunday morning and every time is seems that there is a sequence or at least two consecutive numbers and given that you are pulling 7 balls (including the bonus ball) from 49 balls the chance of having consecutive numbers drawn each and every week is a little fishy but not impossible.
That didn't happen as badly last weekend. The Lottery plus numbers had 24 and 25 but that was all.
But look at the numbers listed in ascending sequence
Lottery: 10 19 24 27 39 49
Lottery Plus: 19 24 25 27 38 49
At first glance you see nothing out of the ordinary but remove the 10 from the Lottery numbers and the 35 from the plus numbers and you have 5 numbers that are the same.
Yes I will conceded that it is possible but the chances of it occurring are quite rare.
Using basic statistics (and I did cheat a bit as my brain had forgotten the formula) I calculated the number of possible combinations of choosing 5 numbers as 1,906 ,844 in other words you have a 1 in 1,906,844 chance of picking 5 numbers.
I will now concede that my statistics is very very rusty and will willingly accept criticism for the next calculation if I am wrong.
What then are the chances of getting 5 numbers the same in two consecutive lottery draws. this I believe is 1 in (1,906,844 X 1,906,844) or 1 in 3,636,054,040,336.
You have a better chance (1 in 750 000) of being struck by lightning than having what happened on 26th February.
So do you trust the organisers of the lottery?
