Experimental probability means we want to calculate probability based on the observations we have. So, to find the "experimental probability" of rolling an even number, lets add up all the even number rolls, then divide that by the total number of rolls in the experiment.
Even numbers are 2, 4, and 6, with 12, 14, and 18 rolls, respectively. This adds up to 12+14+18 = 44 even rolls. The total number of rolls is 13+12+12+14+11+18 = 80 rolls. So, the experimental probability of rolling an even number would be 44/80.
