Pllz me also i will report if you are in for the 1. complete the table by converting each decimal to a fraction. repeating decimals. 0.31 0.125 0.1607 2. describe any patterns you noticed when converting the decimals in the table above.

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.)
