Question 1060275: A bag has
8
green marbles and
8
blue marbles. Half of the blue marbles are made of plastic. A marble is selected at random from the bag. What is the probability that it is a blue, plastic marble? Answer by Edwin McCravy(20060) (Show Source):
There are 4 blue, plastic marbles out of the 16.
Answer: 4 times out of 16 we'll draw one of those.
That's 4/16 or 1/4 of the time, so that's the probability, 1/4
