G = event of picking a green marble Y = event of picking a yellow marble R = event of picking a red marble 1 = event of picking a marble with the number 1 on it 2 = event of picking a marble with the number 2 on it (a) You know that P(G) = 25%, P(1) = 47%, and P(G and 1) = 20%. Find P(G or 1). (b) What does P(G or 1) mean in terms of marbles? (c) You know that P(2) = 53%, P(R or 2) = 68%, and P(R) = 40%. Find P(R and 2). (d) What does P(R and 2) mean in terms of marbles?
