51*32/102=32/2=16.
Therefore, Raina will need 16 cans to cover the court.
Answer: 9) K ||| 10) H
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
Hope this helps :)
Hey,
Depends on what you want us to do with the equation.
If you want us to simplify the expression, here you go:
