45 girls and 60 boys are present at a party. There are 17 girl-boy are in relationship among them. If a girl and a boy is selected at random, what is the probability that they will be not a couple? Pick one:
A) 17/ 2900	B) 2683/2700	C) 2496/2700	D) 2369/2700	E) 198/270
In how many ways we can select a girl and a boy from 45 lady and 60 gentlemen? In 45*60 = 2,700 ways.   We have a total of 17 couples so, the probability of selecting a couple is 17/2,700 = 17/2700.   Probability of there will not be a couple = 1 - (17/2700)   = 2683 / 2700   Ans- 2683/2700
