Try this out and then post your answers - but don't post an explanation. We'll see how people do then explain it later.
Let's say you have 4 cards and the cards are supposed to obey the following rule: If there is a vowel on one side then there is an even number on the other side.
You only want to turn over as many cards as you have to as they are very large and weigh a lot. Which cards do you turn over to see if they obey the rule?
Again don't explain your reasons or give the answer away.
Luck is what happens when preparation meets opportunity ~ Seneca
