The ability to make simple deductions is a prerequisite for good decision-making.

Imagine there are three closed boxes, each full of marbles on a table before you.
They're labeled "all blue marbles," "all red marbles," and "blue and red marbles."
You're told that the labels do describe the contents of the boxes, but all three labels are pasted on the wrong boxes.
You may reach into only one box blindfolded and remove only one marble.

Which box should you select from to enable you to correctly label the boxes?

Doesn't really matter as I'll only be blindfolded for one box. I can look into the other boxes.

Take a marble from the "blue and red" box. If its red, bearing in mind the boxes are incorrectly labelled, it must be from the box of red marbles. Mark that box as "red marbles" and swap the other two over.

Yeah? thumbs up
