Pls no one will how do estimate the numbers im about to give you by rounding to the nearest integer 15.23 - 6.835 and 6.88 + (-8.1) and 80.38 - 24.592 pls

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.)
