Answer 2

The question clearly says that sum of red balls + white balls + blue balls = 12

So, x + 2x + 3x = 12

6x = 12

X = 2balls

So, number of red balls is = x = 2 balls

Number of white balls is =2x = 2×2 = 4 balls

Number of blue balls is = 3x = 3×2 = 6 balls

PROBABILITY OF NOT GETTING WHITE BALL IS :

TOTAL NUMBER OF OUTCOMES = 12

NUMBER OF FAVORABLE OUTCOMES = 12 - 4 = 8

HENCE, THE PROBABILITY IS 8/12 = 4/5
