Hmm, this problem seems a bit tricky. But hey, at least it's not as bad as the time I tried to integrate a function over a Möbius strip. Now that was a real head-scratcher!

Ah, a classic probability problem. Let me grab my calculator and work this out... Okay, got it! The correct answer is C. 0.75. Easy peasy lemon squeezy, as they say.

Hmm, this seems straightforward. The question is asking for the probability that X is greater than 0.5, and the probability density function is given as f(x) = 2(1-x). Integrating that from 0.5 to 1 should give us the answer. I'm going with C.

Okay, let me think this through step-by-step. The probability density function is f(x) = 2(1-x), which is defined over the interval 0 to 1. To find the probability that X is greater than 0.5, I need to integrate the function from 0.5 to 1. That gives me 0.75. Looks like the correct answer is C.
