3. Consider three events A, B and C. Show that P(A ? B ? C) = P(A) + P(B) + P(C) ? P(A ? B) ? P(B ? C) ? P(A ? C) + P(A ? B ? C)

Step 1
This is the probability that either A, B, or C occurs. P(A ∪ B ∪ C) = P(A) + P(B) + P(C) However, this calculation counts the cases where two events occur simultaneously twice. For example, if A and B both occur, they are counted once in P(A) and once in P(B). Show more…

Show that for any three events $A, B,$ and $C$ with $P(C)>0, P(A \cup B | C)=P(A | C)+P(B | C)-P(B | C)-P(B | C)-P(B | C)-P(B | C)-P(B | C)-P(B | C)-$ $P(A \cap B | C) .$

Conditional Probability
Consider any events $A, B,$ and $C .$ Prove each of the following: a) $P(A \cap B) \geqslant P(A)+P(B)-1$ b) $P(A \cup B \cup C)=P(A)+P(B)+P(C)-P(A \cap B)-P(A \cap C)-P(B \cap C)$ $+P(A \cap B \cap C)$
Operations with events
Let $A, B$ and $C$ be three events such that $P(C)=0$. Statement-1: $P(A \cap B \cap C)=0$ Statement-2: $P(A \cup B \cup C)=P(A \cup B)$
