I will assume that your preferred tool is regular calculator TI-83 or TI-84. 

    (A)  p = normalcdf(36000, 56000, 75000, 15000) = 0.098.       ANSWER


    (B)  p = normalcdf(85000, 9999999, 75000, 15000) = 0.2525.    ANSWER


    (C)  p = 0 (or vanishingly small value)  <<<---===  double check if you correctly posed this question.

Solved.
