    Answer:

    0.568

    Step-by-step explanation:

    P( e-book) = 0.28, P(On the bestseller list) = 0.4

    Since event e-book and bestseller list are independent,

    ( Using formula, P( A OR B) = P(A) + P(B) – P( A AND B) )

    P(e-book AND On the bestseller list) = P( e-book) * P(On the bestseller list)

    P( e-book OR on the bestseller list) = P( e-book) + P(On the bestseller list)

    – P( e-book) * P(On the bestseller list)

    = 0.28 + 0.4 – 0.28 * 0.4

    = 0.568
