The empirical probability of an event is the number of times the event occurs divided by the total number of trials. In this case, the event is getting 4 tails, and the total number of trials is 2 + 5 + 12 + 2 + 1 = 22. So, the empirical probability of getting 4 tails is 1/22 = 0.045 (rounded to the nearest thousandth).
