31.16665. if you add all those numbers up, then divide it by the total numbers there were, which was six, hints the sides on the dice, then take the number you got after dividing the total by six, and divide that by 2. do this because there are only 3 even numbers on a dice, which is half of the total numbers of sides, and you get 31.16665

Answer: 52.5%

Explanation:

1) probability = positive events / total events

2) probability of rolling an even number =  # even results / # total rollings

3) # even results = # twos + # fours + # sixes = 62 + 64 + 75 = 201

4) # total rollings = 60 + 62 + 59 + 64 + 63 + 75 = 383

5) probability of rolling an even number = 201 / 383 =0.5248

6) Convert to % by multiplying by 100: 52.48%

7) Round to the nearest tenth: 52.5%

Answer: 52.5%
