Answer:
7/10 or 70%
Step-by-step explanation:
Add the number of each color of balls together to get the total
5 + 2 + 3 = 10
Add the number of all the balls that aren't black
5 + 2 = 7
Then divide how many balls that aren't black by the total. This gives us the probability the ball you choose is not black
7/10 = 0.7 or 70%

X = .5
Step-by-step explanation:
10 × 20 = 200
10.5 × 20 = 210
Explanation:
Y = 210
210 = 20(10+X)
divide both sides by 20
10.5 = 10+X
subtract 10 from both sides
.5 = X
X = .5
