Answer:
In bold, see below
Explanation:
P(Red, Blue) means that there's an 8/27 chance of selecting a red marble, and then a 6/26 chance of selecting a blue marble after eliminating the red marble we just grabbed. Therefore, multiplying the probabilities, (8/27)(6/26) = 48/702 = 0.068 would be the probability of selecting a red marble followed by a blue without replacement.
P(Red, Red) means that there's an 8/27 chance of selecting a red marble, and then a 7/26 chance of selecting a red marble after eliminating the first red marble we just grabbed. Therefore, multiplying the probabilities, (8/27)(7/26) = 56/702 = 0.08 would be the probability of selecting a red marble followed by a red without replacement.
P(Blue, White) means that there's a 6/27 chance of selecting a blue marble, and then an 8/26 chance of selecting a white marble after eliminating the first blue marble we just grabbed. Therefore, multiplying the probabilities, (6/27)(8/26) = 48/702 = 0.068 would be the probability of selecting a blue marble followed by a white without replacement.
P(Yellow, Red) means that there's a 5/27 chance of selecting a yellow marble, and then an 8/26 chance of selecting a red marble after eliminating the first blue marble we just grabbed. Therefore, multiplying the probabilities, (5/27)(8/26) = 40/702 = 0.057 would be the probability of selecting a yellow marble followed by a red without replacement.
