Greetings! The answer is below make sure to read the steps carefully. Hope this helps! C:

Analysis: blue 3                 3+2+4 = 9 total marbles

              red 2

              green 4

Probability of two blue = 3/9 x 2/8 = 1/12 = 3/36

Probability of two red = 2/9 x 1/8 = 1/36

Probability of two green = 4/9 x 3/8 = 1/6 = 6/36

Probability pf two the same = 3/36 + 1/36 + 6/36 = 5/18

The probability of getting two of the same colour is 5/18. In order to determine the percentage you must divide 5 by 18 and mulitply x 100 and round it. (5/18 = 0.2777777777777778 x 100 = 27.77777777777778 about 27%)

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
