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)
Answer:
6 / 5
Step-by-step explanation:
1) you take the 2 feet and change it to inches by multiplying 2 by 12 because there is 12 inches in each foot.
2) you find the greatest common factor of 12 and 10 which is 2
3) you divide both of the numbers by your GCF of 2 which is 6/5
0.7 is just 7 tenths which is literally 7/10.
