A game of darts involves throwing two darts at the board. Hitting a blue region with a dart scores 1 point; a red region, 2 points, a green region, 3 points, and the orange region, 5 points.
Assume that no skill is involved. What is the probability, stated as a fraction in lowest terms, that two randomly thrown darts will score 8 points or more? Justify your answer.

It depends upon the areas associated with the different colors. You have not said that they are equal.
