Analyzing the frequency of Florida Play 4 straight numbers in the same way as we did for 3-digit numbers is ridiculous since there are 10,000 of them and many of them have never been drawn. For example, with 1 draw a day and if assuming that different numbers are drawn every day, it will take more about 27 years to cover all Play 4 straights. So, if a player is playing the same straight number everyday, he shouldn't be surprised if the number doesn't win for 27 years. In fact, this is the most optimistic case. A more elaborate probabilistic analysis reveals that, even in 27 years, the chance of winning with that number is only about 63%. Such analysis further states that a given straight number has a 99.9% chance of winning in 69,074 draws, and that would be about 189 years.
Here is a summary of the actual data pertaining to Florida Play 4 straight numbers. Note that, based on data available on this site, there are 3551 Florida Play 4 straight numbers not yet drawn.
