I HAVE KEYS BUT NO LOCKS I HAVE SPACE BUT NO ROOM YOU CAN ENTER BUT YOU CANT GO INSIDE O INSIDE IDE RIDDLES WITH ANSWERS TO SOLVE - PUZZLES & BRAIN TEASERS

The answer is to let your friend go first. This puzzle is based on an old game/scam called Penny Ante. No matter what you picked, your friend would be able to come up with a combination which would be more likely to beat yours. For example, if you were to choose HHH, then unless HHH was the first combination to come up you would eventually lose since as soon as a Tails came up, the combination THH would inevitably come up before HHH. The basic formula you can use for working out which combination you should choose is as follows. Simply take his combination (eg. HHT) take the last term in his combination, put it at the front (in this case making THH) and your combination will be more likely to come up first. Try it on your friends!
