a bag contains five green marble and three red marbles. if three marbles are chosen at random without replacement, what is the probability that all three will be green?
----------------
# of ways to pick 3 of 5 green marbles = 5C3
# of ways to pick 3 of any sort from 8 marbles = 8C3
--------
Prob(3 green from the bag)=5C3/8C3 = [5*4*3/1*2*3]/[8*7*6/!*2*3] = 0.17857....
