    Answer:

    2/15

    Step-by-step explanation:

    6 red marbles and 4 yellow marbles = 10 marbles

    P ( 1st is yellow) = yellow marbles / total marbles

                              = 4/10 = 2/5

    The marble is not replaced

    6 red marbles and 3 yellow marbles = 9 marbles

    P ( 2nd is red) = red marbles / total marbles

                              = 3/9 = 1/3

    P ( yellow, red) = 2/5 * 1/3 = 2/15
