An urn contains 5 red marbles, 4 blue marbles, and 3 green marbles. A marble is selected at random and then, without replacing the first marble, a second marble is selected at random. What is the probability of selecting a green marble and then a red marble?
Answered by PsyDAG
Green = 3/12

Red = 5/11, because one green marble has already been picked.

The probability of both/all events occurring if found by multiplying the probabilities of the individual events.
