## FAQ

### How Accurate Is The Expected Value Calculator?

**Lottolibrary's expected value calculator gives a good estimation, but not completely accurate.** Some of the factors that can lead to inaccuracies:

- For simplicity's sake the expected value calculator deals only with the jackpot prize: it does not take into account smaller prizes, which can slightly increase the expected value.
- The calculations assume that the number of winning tickets follows a binomial distribution.

### How Does The Number Of Tickets Sold Effect The Expected Value?

**The bigger the number of tickets sold, the smaller the expected value will be.** The more tickets are sold, the more likely it will be to have multiple winners. If there are multiple winners, the jackpot is split among them, so the winnings will be smaller, and the expected value decreases.

### How Does The Price Of A Lottery Ticket Effect The Expected Value?

**The higher the cost of buying a ticket is the lower the expected value will be.**
