7. Find P(A∩B∩C)

The event $A$, $B$ and $C$ are non mutually exclusive. If $P(A) = 0.34$, $P(B) = 0.35$, $P(C) = 0.31$, $P(A \cap B) = 0.05$, $P(B \cap C) = 0.11$, $P(A \cap C) = 0.14$ and $P(A \cup B \cup C) = 0.72$, then find the value of $P(A \cap B \cap C)$.

 

 

The value of $P(A \cap B \cap C)$ $=$ .
