  • In statistics and probability, the formula for expected value is E (X) = summation of X * P (X), or the sum of all gains multiplied by their individual probabilities. The expected value is comprised on two components: how much you can expect to gain, and how much you can expect to lose.
  • So you can say that with simple chance you should expect returns of 36/37 of your stake money, which is the expected value in roulette (97.3%). In other words, for every 100 units staked you will receive back an average of only 97.3 units. There are some casinos which are a little fairer to players who rely on simple chance.

Thus, to compute the expected value sum over all tickets, we just have to count the number of distinct ticket numbers and multiply this value by P / N. In summary, the expected value of each ticket is simply the number of distinct tickets sold multiplied by P / ( kN ), where k is the number of tickets sold so far.
For example, odds of getting 1 number and the bonus are 1:56, which is one success to 56 failures. This means the probability is actually out of 57 events and would be 1:57, which would be 1.75%, not 1.79%; unless they are using the term "odds" to actually mean "probability."
