  • Two events $A$ and $B$ are independent if and only if
  • If $A$ and $B$ are mutually exclusive, then
  • If the events $B_1, B_2, \cdots, B_k$ partition of this sample space $S$ that $P(B_i)\ne 0$ for $i = 1, 2, \cdots, k$)  then for any event $A$ of $S$
  • Let $A_1, A_2, \cdots, A_n$ be $n$ events in an event space. If \begin{align} P(A_iA_j) &= P(A_i)P(A_j) \quad for \quad i\ne j\ P(A_iA_jA_k) &=P(A_i)P(A_j)P(A_k) \quad for \quad i\ne j \ne k\ \vdots &\ P(\cap_{i=1}^n A_i) &= \prod_{i=1}^n P(A_i) \end{align} then the events are called
