jim

Answer 22

what is the probability of drawing 1 green marble?

Answer 23

hint: look at the number of green and the number total

Answer 24

wat

Answer 25

how many green marbles are there

Answer 26

3

Answer 27

out of how many total?

Answer 28

10

Answer 29

so the probability of getting green is 3/10

that's the first draw

Answer 30

on the second draw, we do NOT replace the marble

so we have 2 green out of 9 total

the probability of getting another green on the second draw is 2/9

Answer 31

multiply 3/10 and 2/9 to get your answer

Answer 32

reduce the answer as much as possible

Answer 33

times or addition

Answer 34

multiply means times

Answer 35

i know i didnt read it properly
