A picture measuring 2inches by 3inches is placed inside a frame. the width between the picture and the frame is equal around the entire picture. if the area of the frame and the picture is 72 square inches, what is the width of the frame? Thanks!

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.)
