请问一下大家这题
A certain company has 255 employees. If an employee is to be selected at random from the company’s employees, is the probability less than that the employee selected will be a woman who has a college degree?
(1) 130 of the company’s employees do not have a college degree.
(2) 125 of the company’s employees are men.
我感觉B中得出女生的人数已经小于一半了,那他们当中不管多少人有文凭,这比例肯定小于二分之一呀,但是答案说B不能单独证明,为什么呢
