### Online MCQs Probability Statistics

- 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

$P(A_iA_j) = P(A_i)P(A_j) \quad for \quad i\ne j$

$P(A_iA_jA_k) =P(A_i)P(A_j)P(A_k) \quad for \quad i\ne j \ne k$

$\vdots$

$P(\cap_{i=1}^n A_i) &= \prod_{i=1}^n P(A_i)$ then the events are called - The classical probability method is applied to an experiment that
- The joint probability of two independent events $A$ and $B$ is
- Two mutually exclusive events
- The probability can never be
- The probability of an impossible event is always
- If $P(A \cap B) = 0.12$ and $P(A) = 0.3$, find $P(B)$ where $A$ and $B$ are independent
- For two mutually exclusive events $A$ and $B$, $P (A) = 0.2$ and $P (B) = 0.4$, then $P(A \cup B)$ is
- A standard deck of 52 cards is shuffled. What is the probability of choosing the 5 diamonds,
- When two coins are tossed the probability of at least one head is
- Two cards are drawn at random from a standard deck of 52 cards, without replacement. What is the probability of drawing a 7 and a king in that order?
- $P(A\cap B)=P(A)\cdot P(B)$, then $A$ and $B$ are
- To calculate posterior probability, a data professional can use ———- to update the prior probability based on the data.
- When three dice are rolled, the sample space consists of
- An event that contains the finite number point, the sample space is called
- The total area under the curve in the probability of density function is?
