2.    Your semiconductor company has 2 fabs, Red Fab and Blue Fab.  Red Fab produces 27% of the chips and the larger Blue Fab produces the rest.  There are 100 chips from that population in front of you and they look all the same. a)    If you sample the chips one at a time for a total of 30 times, replacing each chip that you have selected before selecting the next chip, what's the probability of selecting Blue Fab's chips exactly 5 times out of the 30?   b)     What if you sample without replacement?
