Question 831678: A certain type of toy ball is either red or green and is either striped or not striped. If a ball is randomly selected, the
probability that it is red (R) and striped (S) is .2, the probability that it is green (G) and not striped (S) is .1, and the probability that it is striped (S) is .5. Find the probability that the ball is green (G) .
