Explanation:

Step1: Analyze Bag A

Bag A has only red marbles. So picking a red marble is certain.

Step2: Analyze Bag B

Bag B has 1 yellow and 6 red marbles. Total marbles = 1 + 6 = 7. Red marbles are more than half. So picking a red marble is likely.

Step3: Analyze Bag C

Bag C has 3 yellow, 1 red, and 3 blue marbles. Total marbles = 3 + 1 + 3 = 7. Red marbles are the least. So picking a red marble is unlikely.

Answer:

Bag A: certain; Bag B: likely; Bag C: unlikely
