| 1 3 5 -1 |
| 1 -1 -1 3 |

A) (1, 1, -1)
B) (2, -1, 0)
C) (4, 0, -3)
D) (5,1,1)

Asix-sided 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, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)
