    Students

    78 students participate in one or more of three sports: baseball, tennis, and golf. Four students participate in all three sports; five play both baseball and golf, only; two play both tennis and golf, only; and three play both baseball and tennis, only. If seven students play only tennis and one play golf, what is the total number of students who play only baseball?

    1) 12
    2) 44
    3) 56
    4) 60

    Explain.
