Ashley worked part-time in the coffee shop down the street. Her usual shift is 3 4/5 hours per day. But since she needed to go to pick up Bernice, she left work 1 1/4 hours earlier on Thursday and Friday. How much did she work on Thursday and Friday?

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.)
