9. you have a bag with 3 red marbles, 4 blue marbles, and 5 green marbles. you draw 2 marbles out of the bag. without replacing the first marble drawn from the bag, find each of the following probabilities.

p(blue, then blue) p(red, then green)

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
