    Probability Question.

    An aquarium at a pet store contains 20 guppies (12 females and 8 males) and 36 tetras (14 females and 22 males). If the clerk randomly nets a fish, what is the probability that it is a female or a tetra?

    Can it be both?
    56 total fish

    12 female guppies
    36 tetras
    12+36=48
    so 48/56

    If it cannot be a female tetra,
    14 female tetra
    48 previous possibilities
    48-14=34
    34/56
