A bag has 9 red marbles, 6 blue marbles, and 5 yellow marbles. What is the probability of pulling a blue marble from the bag?

Answer 1

A probability is the likelihood of a certain outcome, and is in general the "part divided by the whole"

In this case, we have a total of 20 marbles. The probability of drawing a blue marble is 6/20 = 0.3

In other words, 30 percent of the marbles are blue, so we have a 30 percent chance of drawing a blue marble.
