    How many ways (2)

    A student needs to work five days in January. He does not want to work on more than one Sunday. In how many ways can he select his five working days? (Assume that in the year in question, January has five Sundays.)

    My answer: ^{26}C_5+5*^{26}C_4

    Is this correct?
