From a barrel of colored marbles , you randomly select 5 blue , 2 yellow , 3 red , 4 green , and 2 purple marbles. Find the expreimetal probability of randomly selecting a marble that is NOT yellow . 1. 9 / 16 2. 7 / 8 3. 8 / 9 4. 3 / 4

• armine3313: I think it's 7/8 because there's 16 marbles and 14 aren't blue so you have a 14/16 chance of not getting a yellow marble which simplifies to 7/8

  Answer:

  4/5

  Step-by-step explanation:

  From your experiment of drawing 20 marbles you now have a proportion of non-yellow marbles to total marbles and from that you can come up with an experimental probability that you'll draw a non-yellow marble.  

  P(not yellow) = 16/20  

  But that can be reduced by dividing top and bottom by 4:
