    (D)$81

    Step-by-step explanation:

    Given that the number of purses a vendor sells daily has the probability distribution represented in the table.

    Expected Value, [tex]E(x)=\sum_{i=1}^{n}x\cdot p(x)[/tex]

    Therefore:

    [tex]E(x)=(0X0.35)+(1X0.15)+(2X0.2)+(3X0.2)+(4X0.03)+(5X0.07)\\=0+0.15+0.4+0.6+0.12+0.35\\E(x)=1.62[/tex]

    If each purse sells for $50.00, the number of expected daily total dollar amount taken in by the vendor from the sale of purses

    =Expected Value X $50

    =1.62 X $50

    =$81

    The correct option is D.
