Plz I need help with some Maths?
Dima020 [189]

Before Brian starts messing with them, there are 24 balls in the bag.
9 of them are white.

-- The probability that Brian draws a white ball from the bag is  (9/24) .

If he has already drawn one white ball and put it aside, then there are
23 balls left in the bag, and 8 of them are white.

-- The probability that Brian draws a white ball from the bag this time
is  (8/23) .

So the probability of white balls on both draws is

     (9/24) x (8/23)  = 

              (72/552)  = 

                 3 / 23  =  about <em>13%  </em>(rounded)
