Question

Quizplus · Accepted Answer

The expected value or expected gain in roulette refers to the average amount a person can expect to win or lose over many plays. It is calculated based on the probabilities of winning or losing and takes into account the house edge. It is not the amount you expect to gain on a single play or if you are lucky. It also does not refer to the amount needed to break even over many plays, as this would be the expected value or expected gain of 0.
