    Answer: 0.2; 0.14

    Step-by-step explanation:

    Cynthia had a bag containing

    Red tiles = 2

    Green tiles = 3

    Purple tiles = 4

    Blue tiles = 6

    Total tiles = 2+3+4+6 = 15 tiles

    Probability of drawing a green tile:

    = Green tiles/Total tiles

    = 3/15

    = 0.2

    Probability of drawing a red tile without replacement will be:

    Red tiles/Total tiles

    Total tiles will make be 15-1 = 14

    = 2/14

    = 0.14
