badminton shuttlecock feather
Probability- items from a bag?
A grade 9 class playing badminton in the gym didn't clean up very well after they were done. When the janitor swept up, there were 12 feathered shuttlecocks and 9 plastic shuttlecocks in the pile. They were put in a bag to show to the class the next day. if the 2 shuttlecocks were pulled out of the bag without replacement, determine the probability of the following:
a) 1 plastic and then one feathered shuttlecock
b) 1 plastic and one feathered shuttlecock
c) at least one plastic shuttlecock.
The question is a little confusing to me. Not sure where to begin 
Thanks!
the possibility of just choosing two shuttlecocks out of the bag:
C(21,2)=210
a) you first have to choose one of 9,and then one of 12.it means half the probability of the second part of the question. (because when you choose one plastic and one feathered,there are 2 possibilities:1.u choose the plastic first,2.u choose the feathered one first.so picking the plastic one first has half the possibility of choosing without an order):
C(9,1)*C(12,1)/2
C(9,1)=9 C(12,1)=12 c(9,1)*c(12,1)/2=54
possibility:54/210=9/35
b) twice the possibility of the first one: 2* 9/35 =18/35
c) it means you have to add two possibilities: 1.you pick one plastic and one feathered shuttlecock. 2.you pick TWO plastic shuttlecocks.
1.it's the same as part b.=18/35
2.c(9,2)/54=36/210=6/35
1+2 = 18/35 + 6/35 = 24/35
