Out of 13 applications for a job, there are 5 women and 8 men. It is desired to select 2 persons for the job. The probability that at least one of the selected persons will be a woman is
1) 5/13
2) 14/39
3) 25/39
4) 10/13
Answer: [spoiler]25/39[/spoiler]
This is what I get to know from the question stem:
Out of 5 women and 8 men, we have to select 2 people, out of which at least 1 of the selected person is a woman. The solution states that there are only 2 ways of doing it: (1W and 1M) OR (1M and 1W). My question is: why can I not add one more condition - (2W), so that the answer becomes: (1W and 1M) OR (1M and 1W) OR (2W) ??
1) 5/13
2) 14/39
3) 25/39
