9) This is because at first the probability is 5/14 but once we take one red out we have to account for that so the probability the second time will be 4/13
10) Ming=2/5 Tyrel=5/8
If ming plays 200 they can expect to win (2/5 x 200) = 80
If tyrel plays 200 they can expect to win (5/8 x 200) = 125
To find how how many more tyrel will win than ming just do 125 - 80 = 45
