Abstract: The theory of quantum entanglement has been tested realistically in international laboratories for the past six decades, and the probability function was the main element in determining the final result of the experiment, as well as the percentage of inaccuracy in the experiment was measured to obtain the best performance of the experiment with the theory developed by raising the level of particles Either in our virtual laboratory (VIQEL) we are facing a bigger problem in creating a probability function that is very close to reality and also gives the same percentages of inaccuracy for real experiments to achieve the best results. To enhance the probabilistic results to become closer to the mathematical theory of the probability function, we also attached some graphs for the error curve or the inaccuracy curve and to indicate the permissible global level of error in the experiment, which we relied on in our virtual laboratory. We also proved, through the results provided by the virtual laboratories, the ability to rely on these laboratories to closely converge the results and is able to simulate reality even in the percentage of error and at the level of thousands of particles used in the experiment and for the highest possible accuracy results.
