My Answer: 30choose6=593,775

C. if 6 bottles are randomly selected how many ways are there to obtain two bottles of each variety?
My Answer:
8choose2*10choose2*12choose2=83160

D. if 6 bottles are randomly selext what is the probability that this results in two bottles of each vaiety being chosen?
My Answer:
(8choose2*10choose2*12choose2)/(30choose6)=.140
