Definition of Experimental Probability. Experimental probability of an event is the ratio of the number of times the event occurs to the total number of trials.olution: 1  Step 1: Experimental probability = number of times the event occurs / total number of trials. 2  Step 2: Number of times heads appeared = 27. 3  Step 3: Total number of experiments = 60. 4  Step 4: So, experimental probability of getting a head = 27/60 =9/20.
