To measure 2 liters of milk using a 4-liter and a 3-liter container, first fill the 3-liter container completely. Pour the milk from the 3-liter container into the 4-liter container, leaving 3/4 liter in the 4-liter container. Refill the 3-liter container and pour again into the 4-liter container, but only 1 liter can be added due to the existing 3/4 liter. This leaves exactly 2 liters of milk in the 3-liter container. The method effectively utilizes both containers to achieve the desired measurement.

You could fill the 3 liter container with milk.
Then pour the milk into the 4 liter container, which contains now 3/4 liter milk.
Fill the 3 liter container again with milk.
Then pour again the milk into the 4 liter container, you can only pour 1 liter milk into the 4 liter container because it already contains 3/4 liter milk.
So in the 3 liter container is 2 liter of milk left.

Thanks for the solution :)
 

Thread 'Significant figures for inherently bound values'

I have been insisting to my statistics students that for probabilities, the rule is the number of significant figures is the number of digits past the leading zeros or leading nines. For example to give 4 significant figures for a probability: 0.000001234 and 0.99999991234 are the correct number of decimal places. That way the complementary probability can also be given to the same significant figures ( 0.999998766 and 0.00000008766 respectively). More generally if you have a value that...
