Answer:

-x^8y^2 -2y^7 -2xy^4 -6xy

Eliminate parentheses.

xy^4 + 5y^7 - 6xy - 7y^7 - x^8y^2 -3xy^4

Arrange in descending degree order, group like terms.

-x^8y^2 +(5y^7 -7y^7) +(xy^4 -3xy^4) -6xy

Combine like terms.

-x^8y^2 -2y^7 -2xy^4 -6xy

baherus [9]

You can get a 5 by rolling :
1 and 4
2 and 3
3 and 2
4 and 1

You can get a 9 by rolling :
3 and 6
4 and 5
5 and 4
6 and 3

There are 36 possible outcomes, hence your probability is $\frac{4\cdot2}{36}=\boxed{\frac29}$
