Driving home I was thinking more on the odds of the Kentuky lottery. To pick the three numbers in order is one in a thousand. That is assuming that it is totally random for each number, and that a number is not removed each try (If it was, the odds would be 10 * 9 * 8, or 1-in-720). So the odds of having the same numbers three days in a row would be 1 in 1,000,000,000. Well, bit quite. The odds of having the same numbers two days in a row would be actually 1 in 1000 since the question we are asking is if two numbers are the same between two days, not that they were a certain number on the first day.

So for the same number on three days in a row the odds would be 1 in 1,000,000; but only if it must be those speific days. And this is what it is in most cases. It is not the case when you have a specific number sequence to find. Basic probability and statistics. But applying all this to the real world can get tricky…

Today the fuselage got a lot of rivets knocked into it. Maybe not a huge number, but a lot of fiddly triky ones got done. Sure, we needed to drill too many of them out, but overall it seemed to go really well. One of the final things we did today was to turn the fuselage over, up the correct way. I need to say that the fuselage is now really solid, and looks absolutly amazing. The undercoating inside looks amazing, and it will be soon possible to actually sit in the body and make the engine noises… I got a real sense of achievement over this milestone!
