Question
Your friend claims that the probability of $A$ given $B$ is the same as the probability of $B$ given $A$. How would you convince him that he is wrong?
Step 1
It is denoted as P(A|B) and is defined as the probability that event A occurs given that event B has already occurred. Mathematically, it is expressed as: \[P(A|B) = \frac{P(A \cap B)}{P(B)}\] Show more…

LOGICAL REASONING Your friend does not understand how the product of $a$ and $(b+c)$ is given by both $a b+a c$ and $b a+c a$ Use the properties of multiplication to write a convincing argument to show your friend that both statements are correct.
Properties of Real Numbers
The Distributive Property
a) Prove that if A and B are non-mutually exclusive events, the probability of either A or B occurring is given by P(A or B) = P(A) + P(B) – P(A and B). b) What can you conclude if P(A and B) = 0? Give reasons for your conclusion.
Another of your friends thinks tho mutually exclusive events with nonzero probabilities can never be dependent. Establish whether or not she is correct.
