A relatively well known problem often asked at interviews.
You are told that there is a pack of cards with a letter
printed on one side of each card and number on the other. Four cards are
dealt and show E, 3, T, 8. Which of these four cards do you need to turn
over to test the hypothesis that if a card has a vowel on one side then it has
an even number on the other?
A worthy mention in dispatches for the first DC boy to provide a well outlined solutions, is on offer. Good luck
