How do I calculate the probability of a very basic slot machine?
Hi folks and thanks for taking the time with this one.
For the school fayre we are planning to make a slot machine with three wheels and three images on each wheel. What are the odds or what is the probability of a 'win' ?
Obviously we don't want to make the chance of getting three identical images as likely as a Vegas jackpot, but it would be nice to understand the maths behind such things - just in case there are curious minds on the big day who want to know more. I've looked at the web and read a bit about AND / OR situations for three events happening - tell you the truth I think I need something levelled at the lay-person.
