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)
13 and 14 because 13 squared is 169 and 14 squared is 197
Answer:
4/5 or .8
Step-by-step explanation:
First one: x <= -1
Second one: x > 4/3
Since you logically OR them together, the answer will be simply the combination of them two:
x <=-1 or x> 4/3
