Solution to Three Pixels Walked into a Bar
There are n=3 choices. For a group of k=3 pixels, there are
n x k=9
possible combinations of colors, {RRR, RRG, RRB, RGG …}.
However if one pixel is red, we are left with k=2 and the following
n x k = 6
combinations are possible, RRR, RRG, RRB, RGG, RGB, RBB.
Therefore there is only a 1/6 chance that the group will be neutral, RGB.
Three pixels walk into a bar …
Three pixels walk into a bar together. They met outside and the bartender knows that each pixel can only be red, green or blue. (Multispectrals are welcome, of course, but they wear hats and none are visible.) She also knows that, being noisy pixels, there is an equal chance of any individual pixel being red, green or blue, 1/3. They are wearing coats.
When one pixel removes his coat, the bartender can see that he is red. She wonders about the other pixels and their beverage preferences (e.g., blue pixels often prefer lager). She has no other information, and knows better than to infer from stereotypes.
What is the chance that the group will be neutral (or is it, diverse?), having three different pixels; red, green and blue?
Solution to Boy-Girl Probability Puzzle
For the two-child family, the possible (first, second) outcomes are (BG, GB, GG, BB). Note that the question does not say that the boy you know about is the elder, just that (at least*) one child is male. Order does not matter.
Therefore the last outcome, (G, G) is not possible. The remaining first three outcomes are possible, but only one results in two boys. Therefore the answer is 1/3,
So, if you find out the sex of one child in a two-child family, you can guess that the other child is of the opposite sex and have a better than even chance of being correct.
