Can anybody help me as soon as possible. Model with mathematics. The weight of a pen manufactured at the PEN factory is 8g. The actual weight can vary as much as 2g. Write and solve an inequality to represent all acceptable weights for a pen at this factory. *25 POINTS*

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.)
