大师~来~教我一道SAT题~求详细解答

Of 5 employees, 3 are to be assigned an office and 2 are to be assigned a cubicle. If 3 of the employees are 2 men and are women, and if those assigned an office are to be chosen at random, what is the probability that the offices will be assigned to 2 of the men and 1 of the women? 求详细解答
正确答案为 3/5

Answer 1

两个男的被分到office的概率为2/3 乘以3/5=2/5
一个女的被分到OFFICE 的概率为1/2乘以3/5=3/10
所以总体的概率为2/5乘以3/10等于3/25

Answer 2

5名员工、3要指定一名办公室,2是指派工作隔间。如果3的员工是两名男性和女性,如果这些安排一个机构,随机选择的机率是多少办公室将分为2的男人和1女人?
30％吧
