c) At least one of the 5 support increased funding for public schools?
~~~~~~~~~~~~~~~~~~~ 

(a)  ANSWER :  P = 0.56%5E5 = 0.0551  (rounded).


(b)  ANSWER :  P = %281-0.56%29%5E5 = 0.44%5E5 = 0.0165  (rounded).


(c)  ANSWER :  P = 1 - %281-0.56%29%5E5 = 1 - 0.44%5E5 = 1 - 0.0165 = 0.9835  (rounded).

Solved.

As the formulas are written, they explain everything.
