26

Answer 9

for step c i got 1.85 (and a whole bunch of other random numbers)

Answer 10

and for step d i got 12

Answer 11

so the probability of drawing red is 14/26

I divided the number of red by the number total

Answer 12

i got 7/13

Answer 13

after you draw a red marble, how many total marbles are left?

Answer 14

if u draw 1, that would be 25

Answer 15

Answer 21

there is 12 yellow

Answer 22

i simplified 25/26 and got 0.961538

Answer 23

that is in decimal

Answer 24

in percent it is...

Answer 25

so the probability of picking yellow is 12/25

Answer 26

first draw: probability of picking red = 14/26

second draw: probability of picking yellow = 12/25

Answer 27

multiply them together

(14/26)*(12/25) = 0.25846153846153

Answer 28

okay... i am following u

Answer 29

then just convert 0.25846153846153 to a percent and you're done
