    We must first solve the number of fiction and nonfiction books

    if x is the number of fiction books and

    y is the number of nonfinction books

    Then,

    x + y = 400

    x = y + 40

    Solving the system of equations:

    x = 220

    y = 180

    Therefore, the probability that Audrey and Ryan will get both nonfiction books is

    P = 180/400 + 179/399

    P = 0.8986
