Megapot Expected Value (EV)
Since 70% of all ticket sales fund the jackpot:- If you buy 1 ticket for $1, **$0.70** of it contributes to the prize pool. 30% is paid as fees to the community for building a large jackpot and referring users.
- Each entry has a 100% fair chance of winning. Your odds to win are entry value / jackpot size.
- This means your expected return = 70% of your ticket, or $0.70.
- So EV = $0.70 – $1 = –$0.30
