我算的是 1 = p1-p2 = 0.25(5-1) - 0.25(1-1) = 1 记得不是正确答案，没闹明白为什么。

有NN解惑一下？

(2)      is an even integer.

                  

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D. EACH statement ALONE is sufficient.

E. Statements (1) and (2) TOGETHER are NOT sufficient.
