In a class, there are 15 boys and 10 girls. Three students are selected at random. The probability that 1 girl and 2 boys are selected, is:
Choose the correct choice from the following options:
A) 21/46
B) 25/117
C) 1/50
D) 3/25
E) 4/25
Let S be the sample space and E be the event of selecting 1 girl and 2 boys.   Then, n(S)= Number ways of selecting 3 students out of 25   = 25C3 `   =(25 x 24 x 23)/(3 x 2 x 1)   = 2300.   n(E)= (10C1 x 15C2)   =10 x((15 x 14)/(2 x 1))   = 1050.   P(4/25) =	n(4/25)/n(S)=(1050/2300)=21/46.
