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?

  • Math - ,

    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.
    P(R)=1/4
    P(G)=1/4
    P(R∩G)=(1/4)(1/4)=1/16
