If P(A) = 0.45, P(B) = 0.7, and P(A and B) = 0.65, find P(A or B).
~~~~~~~~~~~~~~~~~


The given data is  INCORRECT  and describe a situation,  which  NEVER  may happen,

because  P(A and B) = 0.65  is given greater than  P(A) = 0.45.


The problem  (as posted)  is  DEFECTIVE  and can not be solved.
