a certain game show has a container filled with balls. Green balls are worth $500, black-$250, red-$450, and yellow-$50. If the container has 12 green, 14 black, 6 red, and 20 yellow balls, what is the probability that a ball that pops out of the container is $250?

250
OpenStudy (anonymous):
12 + 14 + 6 + 20 = ?
OpenStudy (phi):
250 is a "cost"
count the number of balls
OpenStudy (anonymous):
oops i mean 14
OpenStudy (phi):
14 is the number of black balls. we will need that.
but we also need the number of *all* the balls
