Answer 2

Answer:initial: 3 red balls

final: 9 balls

Step-by-step explanation:

Let the number of red balls = X

Total outcomes = 12

Probability to pick red = X/12

Noe, 6 more red balls are added

Total outcomes = 18

Red outcomes = X+6

Probability = X+6/18

Given, the probability when 6 balls are added becomes twice the initial probability

X+6/18 = 2 * X/12

X+6/18 = X/6

6*(X+6)/18 = X

X+6/3 = X

X+6 = 3X

2X = 6

X = 6/2 = 3

Hence the initial number of red balls = 3

After adding 6 more balls, 9 red balls
