3. The joint probability of two independent events $A$ and $B$ is

4. The classical probability method is applied to an experiment that

5. 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 $S$

6. If $P(A \cap B) = 0.12$ and $P(A) = 0.3$, find $P(B)$ where $A$ and $B$ are independent

7. A standard deck of 52 cards is shuffled. What is the probability of choosing the 5 diamonds,

8. The probability of an impossible event is always

11. 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 &\\

• 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

1. Q#8 wrong All of these not correct
because
independent if and only if
P(A cap B)=P(A).P(B)
