Question 436623: There are red, blue and green marbles in a bag. The probability of randomly choosing a blue marble is .3 and the probability of randomly choosing a blue or red marble is .7. If there is a total of 20 marbles how many marble of each color are in the bag? Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! There are red, blue and green marbles in a bag. The probability of randomly choosing a blue marble is .3 and the probability of randomly choosing a blue or red marble is .7. If there is a total of 20 marbles how many marble of each color are in the bag?
----
Solve:
red/20 = 0.3
red = 0.3*20
red = 6
-----
Solve:
blue/20 = 0.7
blue = 20*.07
blue = 14
