Out of 17 applicants, there are 8 boys and 9 girls. Two persons are to be selected for the job. Find the probability that at least one of the selected persons will be a girl.
Choose one:
A) 25/34	B) 19/34	C) 21/34	D) 27/34	E) 37/34
The events of selection of two person is redefined as (i) first is a girl AND second is a boy OR (ii) first is boy AND second is a girl OR (iii) first is a girl and second is a girl.   So the required probability:   = (8/17 x 9/16) + (9/17 x 8/16) + (9/17 x 8/16)   = 9/34 + 9/34 + 9/34   = 27/34.   ANSWER:27/34
