Expected value or expectation of a random variableXis defined, if it exists, in a mathematically precise way with respect to a probability space, typically denoted as(Ω,A,P), whereΩis the universe of possibilities,Athe set of possible events (which are the possible values of the random va...
Here’s the math behind it: The value of winning the season ticket is $199 (you don’t get the $10 back that you spent on the ticket. The odds that you win the season pass are 1 out of 1000. Multiply (1) by (2) to get: $199 * 0.001 = 0.199. Set this number aside for ...
Understand expected values in probability. Learn the formula for calculating the expected value of a random variable. See examples of finding the...
The majority of these people think in a way that is -EV(negative expected value), so most people are getting advice in spots like this from sources who while trying to help them, don’t think in a logical way that will lead to the +EV route(positive expected value). They think in a...
where \(EVWPI\) corresponds to theexpected value with perfect informationand \(EMV^*\) corresponds to the maximum expected monetary value, among all the decision alternatives. The expected value of perfect information is related to theEMV methodand theEOL method, since the expected value of perf...
In poker, we focus on the long run, not the short term. We recognize that the results can vary wildly in small samples, but we know that in the long run the math will bring everything back to its expected value. This means two very important things: ...

Correction:The cost of purchasing every possible ticket combination was miscalculated in the previous version of this post. It has been changed to the correct value. Every so often, the news media becomes all abuzz when a particular lottery jackpot starts to grow really large. Right now is one...
