"If lotteries conduct tests to see if there's an 'indication of a problem', then isn't that the same as seeing if things are working correctly? "
No. Maybe not being able to figure that out on your own is related to your confusion about other things. Whether or not I do things that result in wear and tear to my vehicles depends on whether or not I have a reason to do it. It's really that simple, so there's no reason it should confuse you. I don't think the lottery needs to do as much testing as they do, but it's their choice and there's a logical reason for it even if that logic is based on an inflated concern about the possibility that an unlikely test result indicates an actual problem. Since I'm not an idiot I know that the tests have no effect on the actual results that will determine whether or not I win anything, so I don't care if they do more than they need to.
"That's what you told us in the third post down right here:"
I'm sorry that reality confuses and bothers you, but that's just the way it is. For my part, I don't care. Since I'm not an idiot I know that it's only the winning result that matters, and my chances if winning are the same no matter how many test drawing they do.
"Don't test me by asking me stupid question BOY !"
Aww. I must have hit a nerve. I suppose that's good news, because it indicates that deep inside you have at least a glimmer of recognition that I'm right. About your intellectual and reasoning abilities, that is. I don't see any evidence at all that there's even the barest glimmer of actual understanding about probability.
"the more you flip a coin, and the flips show the same side, the more of a chance it will try to balance itself out."
And there you go again. First, you're apparently not smart enough to have answered the actual question, and second you're claiming yet again that coins have some kind of magical ability to decide whether they should land heads or tails. There are literally millions and millions of past coin flips making it absolutely clear that the next flip is still a 50/50 chance, but there's something about the way your mind works that prevents you from figuring it out.
"But they assume there is something wrong after only 4 or 5 in a row."
You're making assumptions. If you want to know why they do something or what they think you'll have to ask them, because we can only guess about the reasons. My guess is that they've just got a simple policy that when they get a result that's sufficiently unlikely they switch to different equipment because the unlikely result could indicate a problem, not because they're sure it does. They know that every result they get, whether in a test or the official drawing is unlikely, and I doubt that they actually think there's a real problem just because they get a very unlikely result.
As for tests vs actual results, I don't need to guess about whether it's you or them that knows more about the actual probabilities. They know that getting the same number in 8 consecutive drawings isn't particularly unlikely. In fact, they know exactly what the chances are, and they know that's it's orders of magnitude more likely than drawing the same number 5 times in a row during the tests. I do have to guess, but I'm pretty sure you've got no idea how likely it is. Perhaps you're also forgetting that, unlike the 5 test drawings, what you see as the same number 8 days in a row wasn't the result of using the same machine and ball set for each drawing. Of course that doesn't affect the probability, but it definitely has a role in deciding if the repeats are the result of the equipment producing non-random results.
"Call me a conspiracy person"
I thought we established that a long time ago. As near as I can tell what you're doing now is trying to establish that you're just plain crazy.
