On the added picture is given a table of all possible die rolls, for example, under a pair (2,3) you mean that Bo rolls 2 on a die and Amaya rolls 3.
All red shaded cells responds to those choices, when Amaya rolls more than Bo.
Let's count: all possible rolls make up 36 choices and red shaded rolls make up 15 choices, then the probabiliry is

.
Answer: 
.
These answers are all the same equation :/ they are all right, they all go right through the point :/
Answer: They are not congruent.
Step-by-step explanation:
You need to find the distance between these points to find congruence. If just one of these doesn't match with its corresponding side, its not congruent.
DE: square root of 68
_
GH: square root of 53
DE and GH are corresponding, but they are not congruent so these polygons are not congruent.
Answer: b = 10
Step-by-step explanation:
We want a ratio of b/2 that is equal to the ratio of 1/4 to 1 1/4 (or 5/4).
Ratio of (1/4)/(5/4):
(1/4)/(5/4) = (1/4)*(4/5) = 4/20 = 1/5 or 0.2
We want 2/b = 1/5 or 0.20
2/b = 0.20
b = 2/0.20
b = 10

Check: Does 10/2 = (1/4)/(5/4)?
Yes
b is 10
