hi

Question :
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?

i am not been able to figure if following option is enough or not

2) The probability that both representatives selected will be men is less than 1/10

hi --
i noticed that this is your first post.
welcome!
but please read the forum rules: read-before-you-post-general-verbal-folder-guidelines-t2718.html

you can't post problems in this folder without giving the ORIGINAL SOURCE of the problem -- i.e., the company or author that first produced the problem (not, for instance, a forum or other secondhand source on which it has previously been posted).
(this applies to MGMAT problems as well; there are over three thousand problems in our database, so we won't recognize all of them from memory.

please post the original source of this problem within a week, or else we'll have to delete the thread. thanks.
