To solve the question we use the following analogy:
Given that the odds of winning is a/b, then the probability is b/(a+b)
hence to solve the question we proceed as follows:

a]
P(E)=11/36
odds against E=(36-11)/11
simplifying this gives us:
25/11

b] P(E)=31/36
odds against E=(36-31)/31
simplifying this we get:
5/31
hence odds in favor of E=31/5


c]P(E)=32/36
odds in favor of E will be:
36/(36-32)
simplifying the above we get:
36/4
=9/1

d]
P(E)=30/36
odds against E will be:
(36-30)/36
simplifying this we obtain:
6/36
=1/5

e] P(E)=13/36
odds against E will be:
(36-13)/13
simplifying this we obtain:
23/13

Please explain how you got the answer
Flura [38]
\bf (-y+4)(2y-1)\implies \stackrel{(-y)(2y-1)}{-2y^2+y}~~+~~\stackrel{(4)(2y-1)}{8y-4}\implies -2y^2+9y-4

notice, just like in any multiplication, you can simply multiply each term of either polynomial times the other, sum them up and then cancel like-terms.
