Q #1: A bag contains three green balls, four red balls, and six yellow balls. If one ball is randomly selected from the ball, which of the following is the probability that the ball is yellow?

A. 10/13

B. 4/13

C. 3/13

D. 6/13

Answer Explanation
Q #2: Which of the following is the value of x in the equation below? (left|3x-7 ight|-13=2)

A. x = 21/3, x=22/3

B. x = 7/3, x=9/3

C. x = 15/2, x=9/3

D. x = 22/3, x=-8/3
Answer Explanation
1. Add 13 to both sides to isolate the absolute value term, resulting in ( left|3x-7 ight|= 15)
2. Consider two cases:
  - When (+(3x-7)) is positive, solve for x to get (3x = 15 + 7) then (3x=22) (finally x=frac{22}{3})
  - When (-(3x-7)) is negative (but the absolute value makes it positive). Solve for x to get (-3x = 15 - 7) then (-3x=8) (finally x=- frac{8}{3})
So, there are two possible solutions: (x=frac{22}{3} or x=- frac{8}{3})
Q #3: Solve for p in the equation above.

A. p=1/v * (q - x/y)

B. p=1/q * (v - x/y)

C. p=qv+x/y

D. p=qx-vy
