    5/156

    Step-by-step explanation:

    First, how many pieces?

    1 red + 5 green + 7 yellow = 13 pieces

    We draw a piece

    The probability it is green

    P (green) = number of green / total

    = 5/13

    Now there are only 12 pieces left

    Probability the second piece drawn is red

    P (red with 1 piece removed) = number of red / total left

    = 1/12

    P (green, then red) = P (green) * P (red with 1 piece removed)

    = 5/13 * 1/12

    =5/156
