Solve the absolute value inequality for y: 1.-2< |x|-y
2.4 ≥ -y +|2x-1|
3.-3y+6>|x-3|-6
4.2y<|6x|-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.)
