b. Mean=average. Add all of the numbers together then divide by 12, you get about 70.2
c. Median is the middle number, or average of middle 2 numbers. average of 63 and 70 is 66.5.
d. There are 5 months with temperature less than 70, so the chance is 5/12

Discussion:
The real roots of the polynomials are factors of the last term (6) divided by the first term (1). The factors of 6/1 or 6 are 1,2,3, and 6. I found by substitution that x= 1 was a solution, divided the polynomial by x-1, came up with a quadratic (x^2 + 5x + 6), and found the remaining roots via the quadratic formula.
Thank you,
