    Round 1

    P(will get a blue chip)=2/13
    P(will get a red chip)=5/13
    P(will get a green chip)=0
    P(will get a yellow chip)=6/13

    Round 2

    P(getting pink chip)=0
    P(getting yellow or green chip)=6/13

    Blue chips = 3
    Red chips = 2
    Green chips = 3
    Yellow chips = 1

    Total = 9 chips

    ROUND ONE :
    P(will get a blue chip) = 3/9
    = 1/3
    P(will get a red chip) = 2/9
    P(will get a green chip) = 3/9
    = 1/3
    P(will get a yellow chip) = 1/9

    ROUND TWO :
    P(will get a purple or grey chip) = 0
    P(will get a yellow or green chip) = 4/9
    P(will get a red or blue chip) = 5/9
    P(will get a hot pink or orange chip) = 0
