    Answer:

    The probabilty of selecting a red or yellow marble is 7/12

    Step-by-step explanation:

    To know the probability we have to divide the number of favorable events by the number of possible events

    F = Favorable events: red or yellow marble

    P = Possible events:  red, yellow or blue

    F = 4 + 3

    F = 7

    P = 5 + 4 +3

    P = 12

    7/12

    The probabilty of selecting a red or yellow marble is 7/12
