This project generates a sample of 200,000 random numbers using the Random block. Another Random block tries to predict the first number of each random number. The accuracy is usually from 11.1 to 11.2% This project calculates the accuracy to 4 decimal digits.
Using a smaller sample, accuracies of 20% or more are possible. But I used a very large sample to avoid any flukes. A better pseudorandom system to predict this could be made and I have seen a few of them. 100% me. Use with credit to @GamerSteven
