I've been playing in a charity darts competition today.
Raffle tickets were sold in aid of the charity. Several books of tickets were sold. With 10 prizes up for grabs.
At draw time, after the first 5 prizes had been claimed certain people queried as to whether the correct numbers had been entered into the random number generator machine. It transpired that the end number had in fact been entered incorrectly, meaning at least 90 numbers were NOT in the draw.
What do you think should've happened in this scenario?
After the realisation of the error, the ending number was corrected on the machine.
It then transpires after the completion of the raffle, that because the machine wasn't powered off then on again, the change of ending number had no effect. Therefore the 90 numbers were never in the draw.
