20 14, how to divide the three y segments of the postgraduate mathematics, and the difference between FY(y) and (0, 1, 2).
According to the different values of x, y is a uniform distribution on 0- 1 and a uniform distribution on 0-2 respectively.

Even if you flip a coin,

When facing up, y is evenly distributed on 0- 1

When the reverse side is up, y is evenly distributed on 0-2.

So generally speaking, the probability that y is 0- 1 is greater than the probability of 0-2, which can be felt.

When answering questions, according to the definition of distribution function, the result is consistent with our initial feeling.
