Answer:
Box A contains 6 red balls and 4 blue balls,
Probability of red in Box A = 6/10
and Box B contains 4 red balls and 8 blue balls.
Probability of red in Box B = 4/12
A die is rolled, if the number is less than 3, a ball is selected from box A.
Probability of getting 1,2 on dice = 2/6 = 1/3
If the result is 3 or more, a ball is selected from Box B.
Probability of getting 3-6 on dice = 4/6 = 2/3
What is the probability that the ball will be red and selected from Box B = 4/12*2/3 = 2/9
