The question is null, what's the answer?
I skipped the question, and it turns out the answer is both null and null (the green ticks are the correct answers).
So the only way to fail the (analogy) coin toss was for it to land on its edge, and you somehow managed to do that?
If he was supposed to select all correct answers to get the score, then the only way to win is to split the coin in half (cutting parallel to the surface), then throw two pieces up and have both land with their outside faces up. I don't blame @loopback0 for not doing that.
