The total number of ways the study can be selected is: 637065
Given,
Total number of women in a group= 13
Total number of men in a group = 12
Number of women chosen = 8
Number of men chosen = 8
∴ the total number of ways the study group can be selected = 13C₈ and 12C₈.
This in the form of combination factor = nCr
∴ nCr = n!/(n₋r)! r!
13C₈ = 13!/(13 ₋ 8)! 8!
= 13!/5!.8!
= 1287
12C₈ = 12!/(12₋8)! 8!
= 12!/5! 8!
= 495
Now multiply both the combinations of men and women
= 1287 × 495
= 637065
Hence the total number of ways the study group is selected is 637065

Answer: 1733.33 ≈ 1734 applicants
Step-by-step explanation:
Let x be the number of job applicants being looked at.
If 25% of applicants become job candidates, then number of job candidates = 0.25x
If 20% of job candidates receive job offers, then the number of job offers = 0.20 × 0.25x = 0.05x
If 75% of job offers are accepted, then number of accepted recruits = 0.75 × 0.05x = 0.0375x
This 0.0375x shows the number of new recruits which is equivalent to the 65 that is needed by the client if the recruiter.
By equating this 0.0375x to 65,we have:
0.0375x = 65
x = 65/0.0375
x= 1733.33 applicants, for whole number sake because we're dealing with humans, we approximate to 1734
