if u risk $1 to win $2, and ur chances of winning is 50%
whats ur EV in terms of $
im not sure if its $0.50 or $1
currently i think its .50 because
50% * $2 = 1,
less 50% * $1 = .50
= .50
so if we flippin coins in this matter i think my EV is 50 cent, is that correct?
EDIT: Trying to find EV per flip if topic is a bit badly worded

i think your EV is 1$
you win: you have 2$
you lose: you have nothing
hence an EV (average) of 1$ |

I sometimes fold AA preflop to balance my range | |

your EV in a 50/50 situation is always equal to you investment |

you win $2 for every $1 you lose
your EV in terms fo $ is exactly $0.5 because you average 50 cent per flip |

Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. It is our light not our darkness that most frightens us and as we let our own lights shine we unconsciously give other people permision to do the same | |

a quick formula I made up which should work for any case
Convert % to win to decimal eg. 50% = .5 // 83% = .83
ev($) = (% to win as decimal)*(return on win) - (% to lose as decimal)*(amount you lose each time)
quick example
risk 4 to win 5 80% of time we win
ev = 5(.8) - 4(.2) = 3.2
meaning each time we take this risk we mathematically win 3.2 |

Have you ever wondered which hurts the most: saying something and wishing you had not, or saying nothing, and wishing you had? | |
