Proportion in Probability

Jamuni visits a stall where 3 buckets are kept. Bucket A contains 2 red balls and 4 yellow balls. Bucket B has 4 red balls and 8 yellow balls in it. Bucket C has 7 red balls and 14 yellow balls in it. Jamuni and her friends came up with interesting questions and they are discussing these.

Aman asked Jamuni: “If you pick out one ball from each bucket, what is the probability that the ball will be red?” Enter your answers for each bucket in the table below.

Do you see any pattern in the last column of the table? Can you explain why you see this pattern?
