Determine if the expression m+m^3-8m^4m+m ^3 −8m ^4 is a polynomial or not. If it is a polynomial, state the type and degree of the polynomial.

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.)
