Total Marbles = 8 + 6 + 12 + 10 = 36
Probability the marble is blue = 8/36
Inverse this to get the probability of the marble not being blue
Probability of the marble not being blue = 28/36 = 7/9

Answer:
25%.
Step-by-step explanation:
Let E be the event that the dart lands inside the triangle.
We have been given that a rectangular board has an area of 648 square centimeters. The triangular part of the board has an area of 162 square centimeters.
We know that probability of an event represents the chance that an event will happen.




Convert into percentage:

Therefore, the probability that dart lands inside the triangle is 25%.
We must solve <span>2/5 ≥ w -3/5. Note that w is already +, so leave it where it now is. Add 3/5 to both sides of this inequality:
2/5 + 3/5 </span>≥ w - 3/5 + 3/5
Then: 1 ≥ w, or w ≤ 1 (answer)
