Hi
15 chips: 5 red, 7 white, 3 blue
19) If you draw four chips with replacement, what is the probability that all four are white? (7/15)^4
20) If you draw four chips without replacement, what is the probability that all four are white? 
21) If you draw four chips without replacement, what is the probability that at least one of the chips are not white?
1 - p(no white) = 1 - 4red, 3red1blue, 2red2blue, 1 red3blue
=1 -
