290. A jar contains only B black marbles, W white marbles, and R red marbles. If one marble is to be chosen at random from a jar, is the probability that the marble chosen will be red greater than the probability that the marble chosen will be white?
1) r / (b + w) > w / (b + r)
2) b-w > r
1) r / (b + w) > w / (b + r)
2) b-w > r
