Tuesday Teaser #1
Having done an Oxford maths degree, I’ve heard my fair share of good logic puzzles and so I thought it would be a good idea to post some of my favourites on a regular basis in this Tuesday Teaser series. Here’s the first one to kick-off with:
I am a contestant on Deal or No Deal. I am only concerned with winning the top prize of £250,000, so I am delighted to get to the final two boxes with the £250,000 prize left remaining. I say “No Deal” to the banker’s measly offer of £75,000 and am, as is usual, given the chance to choose to keep my box or to switch to the other remaining box. At this point, I consult with one of my friends in the audience and he advises me that in this situation I should always choose to switch boxes, saying that there is a higher chance of the £250,000 top prize being in the other box. Is he right? And why?
This discussion came up at work last week and may well sound very familiar in that it is similar to another famous problem. All will be revealed (along with another Tuesday teaser) next week.
