In a class, there are 15 boys and 10 girls. Three students are selected at random. The probability that 1 girl ande 2 boys are selected is:
Choose the correct choice.
A) 21/46
B) 25/117
C) 1/50
D) 3/25
E) 7/15
Let S be sample space and E be event of selecting 1 girl and 2 boys   Then n(S)=25c3   =2300   n(E)=10c1x15c2=1050   P(E)=2300/1050=21/46   21/46NSWER 21/46 21/46
