The exact question is: You need an 8-sided die for a game. You only have a coin, two four-sided and one 10-sided dice. How can you replace the 8-sided die? Re-rolls are not allowed.
There are several solutions to this I've been told, I found one, but my solution wasn't one of the expected solutions. What solutions can you think of?
My solution was:
Roll 10-sided and 2x 4-sided dice, sum up the result and roll and substract 2-sided die (the coin) which you divide by 2 at the end to get the result (round up)
