第十四套里面一道DS题
If 2 different representatives are to be selected at random from a group of 10 employees and if p is the probability that both representatives selected will be women, is p > 1/2?
(1)      More than 1/2 of the 10 employees are women.

(2)      The probability that both representatives selected will be men is less than 1/10.
    
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.
我算的是E，可是答案是B，第二个条件怎么算男员工都可能是3个，如果女员工是7个的话，p是小于1/2的。。。求高人解答。。。
