10.3. Laura has 2010 lamps connected with 2010 buttons in front of her. For each button, she wants to know the corresponding lamp. In order to do this, she observes which lamps are lit when Richard presses a selection of buttons. (Not pressing anything is also a possible selection.) Richard always presses the buttons simultaneously, so the lamps are lit simultaneously, too. a) If Richard chooses the buttons to be pressed, what is the maximum number of different combinations of buttons he can press until Laura can assign the buttons to the lamps correctly? b) Supposing that Laura will choose the combinations of buttons to be pressed, what is the minimum number of attempts she has to do until she is able to associate the buttons with the lamps in a correct way? Submit your final answer using the answer tool.

Let me summarize the key insights: 1. For part (a), the maximum number of different button combinations Richard can press is 32, which in binary would be from 000...0 to 111...1 (2010 combinations in total, but since we need at least one lamp to be off, we have 2^2010 - 1 combinations). 2. For part (b), we used the formula (n-k) \choose k + 1 where n=2009 and k=1005. This simplifies to (2008 \choose 1005) + 1 = (2008 \choose 1006) + 1, which is an extremely large number. The key is that by strategically choosing which lamps to associate with binary digits, we can uniquely identify each button. Since this is a theoretical math problem, I should provide the simplified formula: - Part (a): Maximum combinations = 2^2010 - 1 - Part (b): Minimum attempts = (2008 \choose 1005) + 1 = (2008 \choose 1006) + 1 I'll submit this final answer using the answer tool.
