You know nothing about the content of the jar. What odds would you take?&lt;p&gt;Now, you see ten white balls get added, then are blinded while other balls are added (maybe). You estimate the jar can&amp;#x27;t hold more than about a hundred balls. What odds would you take?&lt;p&gt;Now, you see ten white and ten black get put in, and saw it was empty before. What odds?&lt;p&gt;Now, you see ten white and fifty black, but the whites are larger, and you get to draw a ball. What odds?&lt;p&gt;The difference between the second-to-last and the last is the missing information we usually think of when we talk about randomness being missing information.&lt;p&gt;And you&amp;#x27;ll see that the previous scenarios don&amp;#x27;t change anything about that.</text><parent_chain><item><author>st1x7</author><text>&amp;gt; the probability of that coin toss being 50% does not talk about the coin; it talks about you, and about your partial knowledge of the universe.&lt;p&gt;But it does talk about the coin - a weighted coin would have a different probability.

If in reality, there&amp;#x27;s one white ball and nine black - then your math is still right, but your model is wrong.&lt;p&gt;If you do experiments with the wrong model (assuming 50&amp;#x2F;50, getting samples from 1&amp;#x2F;10) - your best conclusion would be the model is wrong.&lt;p&gt;But for many settings, you&amp;#x27;d end up declaring your container or the hand used to pull out balls has magical powers. (and to borrow from Douglas Adams go on to prove that black is white, and get killed in the next zebra crossing).</text><parent_chain><item><author>st1x7</author><text>&amp;gt; the probability of that coin toss being 50% does not talk about the coin; it talks about you, and about your partial knowledge of the universe.&lt;p&gt;But it does talk about the coin - a weighted coin would have a different probability.
