If Allisya's mother has an average of 7,000 steps this week, and it is Saturday, how many steps does she have to do tomorrow to get a 10,000 step average for Sunday?

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.)
