Hi,
Im very curious how to compute exact probablility of a certain slot machine games? Even samples will do.
Thanks...

Depends on :
the number of row of slots that spins.
the number of different symbols.
I think generally it would be :
let N = number of spinning slots;
let S = number of different symbols.
then the probability that one will get the same symbol N times
in a row is = 1/N * 1/N * 1/N ... up until there is S number of 1/N.
Simplify it and get : (1/N)^S; where S is the number of symbols,
and N is the number of slots per slot machine.
Lets try it. Say there are 13 different symbols, 1,2,3,4..j,q,k,A
Say there are 3 different slots that spins.
Then the odds that will get A A A is (1/13)^3 = 0.000455166136.
which is really low. Note (1/13)^3 = 1/13 * 1/13 * 1/13.

They are not rigged. Do research before you answer some question
that you are not 100% sure.

In Australia the law states that gaming machines must have a return to player ratio of at least 86%. That is, over the long term, every $1 spent wins 86 cents (or loses 14 cents) per spin on average. In some sense this means that they are not truly random. I'm not saying they are rigged, but the mathematics behind them is not as simple as the example previously given.
However for exercise purposes the equations given can be used to determine a particular result for a single spin in a truly random set of results.

Once I saw an article in Scientific American about this. The gist of it was: In modern slot machines, the wheels are just for show. The electronics inside control what comes up, and they can be (and are) set to give whatever probabilities desired for the wheels.
