Question 1195823: 1. If P(A) = 0.45, P(B) = 0.7, and P(A and B) = 0.65, find P(A or B).
This is a question on my homework. I had no idea that probability (A and B) could increase like this, if it can how do I answer this question?

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.
