If you ask the question, what's the odds of picking the blue ball from bag 1 and what's the odds of picking the blue ball from bag 2, it's 1/5 and 1/6 respectively.
However the question asked was what is the chance of picking the blue ball from both bags (regardless of the fact it's two unrelated actions) and it's 1/30.
Well explained
