Lottery Ev
A precise tool.
What is the Lottery Ev & How does it work?
Understanding the expected value (EV) of a lottery ticket helps players see whether a game is mathematically favorable or not. The EV is calculated by taking the probability of winning the jackpot, multiplying it by the jackpot amount, and then subtracting the cost of the ticket. If the EV is positive, the ticket offers a theoretical profit over many plays; if negative, the game is a loss on average.
EV = \frac{J}{N} – P
J = jackpot amount, N = total possible ticket combinations, P = ticket price
