Answer:
D. 2/3
Step-by-step explanation:
The probability if 4 out of six chance or 4/6. This is because you could roll a 3,4,5, or 6 which is greater than two. 4/6 simplifies is 2/3.
5x + 7x = 180 ⇒ properties of linear pair
12x = 80 ⇒ addition property (since (5 + 7)x = 12x)
x = 15 ⇒ Division property (since we divide both sides by 12)
