This is video #1 of my 'Daily Math Puzzle' series. The questions are intended to be brain teasers or puzzles of varying difficulty for those interested in recreational math and puzzle solving.
In this question, we have the digits one through five that must be arranged in a star pattern. We want to consider all such possible diagrams.
We are interested in finding the probability of selecting a diagram at random so that at least one edge links consecutive numbers.
