Working together, Scott and Amy can dig a 10 ft by 10 ft hole in 4.44 hours. Had
she done it alone it would have taken Amy
cight hours. Find how long it would take
Scott to do it alone.

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.)
