When playing the lottery, you must select two numbers between eight and fifteen. These numbers can be chosen randomly, or they can be your favorites. The smaller number does not have to be listed first, but it must be between 8 and 15 and cannot be greater than the total. Similarly, you cannot pick the same lottery number twice. To choose the winning lottery number, you must select two numbers between 8 and 15 that are equal to each other. In addition, the numbers must be within 15 percent of each other.

To determine which lottery number to play, look at the first character of the hexadecimal string. Lottery numbers with 0-3 are considered lucky, while numbers starting with c-f are not. The quartile of lottery numbers is based on the number of current residents. By studying the first four digits, you will learn which lottery number has the most chances of winning. You can also look at the pattern of lottery numbers and see which ones were drawn recently.

The DOE uses a single lottery number for all schools, which has been shown to increase the probability of matching to the top choice. This is based on literature that shows that students with a good lottery number are more likely to be assigned to the school they choose if the lottery is conducted separately for each school. The chances of a student being assigned to their top choice are lower than with separate lotteries, and the probability of being rejected are roughly equal.
