The Rocket Coaster has 16 cars, some that hold 6 people and some that hold 8 people. There is room for 106 people altogether. How many of each car are
there on the Rocket Coaster?

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.)
