EV = Expected Value.
For every action dependent on probablity (P), there is a % of it happening it. So if we flip a coin for $1 a wager now there is $2 wagered and my chance of hitting is 50%.
$2P-$1=EV
$2(50%)-$1=0
Thus, you will breakeven.
For every action in probability, there will be 1 or more possible outcomes.
EV = the mean of all possible outcomes.
Let's say we flip that coin 200 times. Our EV is 0, yet it is feasible someone wins all $200. So, while there are many outcomes, EV is just the mean of these.
