The question posted by me mentions of how many of the possible groups of 4 TEMPORARY employees consist of 3 women and 1 man.
We dont know what is the breakup of man & woman for temporary employees after 4 are made permanent.
The initial post was mis-worded. Look at Mitch's and Brent's cleaned up version. (There are 12 temporary employees, 4 of whom will be selected to become permanent employees.)ash4gmat wrote:Dear Experts,

It's just mentioned to give the 4-person group a label, but the label is incidental to the calculation. In essence, we have a pool of 5 women and 7 men. From this pool we want to know how many ways we can form a 4-person group of 3 women and 1 man. It just happens to be the case that those 4 people are being selected to become permanent employees. If those 4 people were being selected to form a dodgeball team or to go to the moon, etc., the math would be the same.David if 4 permanent employees have no significance then why it is mentioned in the question?
Since 5 of the 12 temp employees are women, there are 7 male temp employees. We need to determine the number of possible groups of 4 temp employees that will consist of 3 women and 1 man. Since we have 5 female temp employees and we need to pick 3 of them, the number of ways we can do this is 5C3 since the order of their selection doesn't matter. Similarly, since we have 7 male temp employees and we need to pick only 1 of them, the number of ways we can do this is 7C1. Finally, to find number of possible groups of 4 temp employees that will consist of 3 women and 1 man, we multiply 5C3 and 7C1:ash4gmat wrote:Q.Of the 12 temp employees in a certain company,4 will be hired as perm employees.If 5 of the 12 temp employees are women,how many of the possible groups of 4 temp employees consist of 3 women and 1 man.
