The subjects of this study are four lotto games: 6/42, 6/45, 6/49, and 6/55. To play these games, you pick 6 numbers out of 42, 45, 49, or 55 consecutive numbers beginning from number 1. Depending on your area, you may win a prize if you matched at least 3 numbers.

For each lotto game, except 6/55, I sampled more than a thousand jackpot numbers. The table below shows the number of each sample and the margin of error.

Lotto | Sample | Margin of Error |
---|---|---|

6/42 | 1149 | 2.95% |

6/45 | 2096 | 2.18% |

6/49 | 1903 | 2.29% |

6/55 | 180 | 7.45% |

The margin of error can range between 1% and 10%. In Statistics, the larger the size of the sample, the closer its characteristics would be to the characteristics of the entire population.

#### Observation

Winning numbers are mechanically drawn from a tumbler using air pressure that blows the ball up and out of the tumbler. If the balls have varying weight, the lightest balls would always win. For that reason, all balls weigh almost precisely equally. There are other factors that may affect the drawing of a ball. These are humidity, dirt, paint, perspiration, and pressure. In this study, we will disregard these factors for the reason that we can not gather data related to these.Provided that your local lotto system uses the same drawing method mentioned previously, we can assume that our findings may be close to your own lotto system. If you wish to be more precise, you can use a tool that allows you to enter the history of lotto drawings in your own area. You can download this tool at lottotips.amikvs.com.
