    7/15

    Step-by-step explanation:

    Probability of an event is the number of possible outcome divided by the total outcome. It is a ratio. The probability that an event will or will not happen is 1 as those are the only two possibilities.

    Given that the flower shop has 11 red roses, 7 pink roses, 9 white he roses, and 3 yellow roses in stock, the total number of flower available

    = 11 + 7 + 9 + 3

    = 30 flowers

    The probability that a rose selected is;

    red = 11/30

    yellow = 3/30

    the probability they the selected rose is red or yellow

    = 11/30 + 3/30

    = 14/30

    = 7/15
