Simulates 10,000 "random walks"; the number starts at 0 and repeatedly either (with an equal chance) increases or decreases by 1. This continues until the number reaches 10 or -10. The "Probability List" shows the simulated probability of the run reaching 10 or -10 after reaching (the corresponding list number - 10). Margin of error compared to expected results is ~+-0.07%. Use Turbo Mode for ultra-fast simulating.
