A reference similar to the term expectation. Often, when using the term expected value,
players also include the additional value that may result from comps earned during play.

For example, if your chance of winning a $100 pot is 50%, your expected value in that pot is $50.
Also, equity. Sometimes shortened to EV.




Expected Value (videopoker)

The statistically projected average per-unit-bet payback of a particular play. Another way of looking at the
EV is the average of all possible outcomes for a particular play or game. Most commercially available video poker
analysis programs give the Expected Return (ER) of each possible play when a hand is analyzed. Assuming a five coin bet,
dividing the ER by five will give the EV. A better technique, however, is to change the bet to one coin and adjust all
one-coin payoffs to per-coin values so that the program will give EV directly. For more details, see my article "What is Expected Value?"
