Given that P(A) = 0.7, P(B) = 0.6 and P(A and B) = 0.35, which one of the follow statements is incorrect?
1. P(B')=4
2. A and B are not mutually exclusive
3. A and B are independent
-----------
4. P(B/A)=0.6 ?
P(B|A) = P(A and B)/P(A) = 0.35/0.7 = 0.5
-----------
5. P(A or B)=0.95
==================================
Ans: #4 is incorrect.
