Answer:
2/9
Explanation:
Box A has 6 Red and 4 Blue balls - Probability of getting a Red is 4/10 = 2/5
Box B has 4 Red and 8 Blue balls - Probability of getting a Red is 4/12 = 1/3
You roll a dice, Probability of getting less than 3 is 2/6 = 1/3
Probability of getting 3 or more is 4/6 = 2/3
So, the Probability of picking from Box B is when you roll 3 or more which is 2/3, and the probability of getting red from Box B is 1/3.
Combining together, 2/3*1/3 = 2/9.
