A die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. In the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, then 5 times, and finally 7 times. Which experimental probability is consistent with this simulation?

The probability of getting 3 is 15%.

The probability of getting 3 is 30%.

The probability of getting 3 is 45%.

The probability of getting 3 is 60%.
