PLZ help , will MEDAL+FAN for BEST response. A bag contains 12 green marbles, 18 red marbles, 13 white marbles, and 7 black marbles. What is the probability of drawing a red marble out of the bag?

OpenStudy (rainbow_rocks03):

No direct answers I want the explanation too.

OpenStudy (lana_mk):

18:50. the number of red marbles to the total number of marbles.

OpenStudy (rainbow_rocks03):

so you are saying 18:50 is my answer @lana_mk ?

OpenStudy (jennyrlz):

hello :)

OpenStudy (lana_mk):

yes.

OpenStudy (rainbow_rocks03):

Well that is wrong. that is not an answer choice.

OpenStudy (jennyrlz):

@lana_mk is correct

OpenStudy (lana_mk):

@jennyrlz thanks :)

OpenStudy (jennyrlz):

how you do it is add all the marbles together (50) and then divide it the red ones by this number 18/50

OpenStudy (jennyrlz):

np :)

OpenStudy (jennyrlz):

but this can still be reduced

OpenStudy (jennyrlz):

9/25

OpenStudy (lana_mk):

9:25 i think is the most it can be reduced to

OpenStudy (jennyrlz):

is that a choice?

OpenStudy (rainbow_rocks03):

OpenStudy (jennyrlz):

C

OpenStudy (lana_mk):

It would be 9/25 then.

OpenStudy (rainbow_rocks03):

How can you reduce 18:50 into 9/25 ?

OpenStudy (jennyrlz):

divide both sides by 2

OpenStudy (lana_mk):

they both can be divided by 2

OpenStudy (rainbow_rocks03):

oh

OpenStudy (jennyrlz):
