Law of large numbers: the more trials you run, the closer each outcome gets to its theoretical probability.
Enter numbers separated by commas or spaces and click Calculate to get the mean, median, mode, variance, standard deviation, range (min–max), sum and count, with the sorted dataset shown below. For probability, pick Coin flip or Dice roll, set the number of trials and click Simulate — each outcome's observed frequency approaches its theoretical probability (coin 50% / dice ≈ 16.7%) as trials increase.
