Let B(α, β, γ) represents that a bag B contains α red balls, β green balls and γ blue balls,\. Given B1(2,3,2),B2(3,2,2),B3(2,2,3). A die is rolled. If the die shows up 2 or 3 or 5, then a ball will be drawn at random from bag B1. If the die shows up 4 or 6, then ball will be drawn at random from bag B2. If the die shows up 1, then from bag B3 a ball will be drawn at random. Then the probability of drawing a green ball from a bag thus chosen is
