<h3>
Answer: C) 25%</h3>
Explanation:
There are 7 blue out of 5+7+6+10 = 28 chips total.
7/28 = 1/4 = 25/100 = 25% is the probability of pulling out a blue chip.
Here is the set up:
10,955 = x^2 -20x + 30
Solve for x to find your answer.
13×10=130
13-10=3
13 and 10 is the answer
100+100+114 +x+x = 540
314 + 2x = 540
X= 113
Hope this helps!
