given a jar contains four marbles, each a different color: red, blue, green, and yellow. If you draw two marbles from the jar, one after another, replacing the first before drawing the second,what is the probability of getting a red marble on the first draw and a green marble on the second draw?

Since there is replacement of the marbles, the two draws are independent. The joint probability of two independent events is the product of the individual probabilities.
