A die is rolled. Let $E$ be the event "die shows $4$ " and $F$ be the event "die shows even number". Are $E$ and $F$ mutually exclusive ?
When a die is rolled, the sample space is given by
$S =\{1,2,3,4,5,6\}$
Accordingly, $E =\{4\}$ and $F =\{2,4,6\}$
It is observed that $E \cap F=\{4\} \neq \phi$
Therefore, $E$ and $F$ are not mutually exchasive events.
A die has two faces each with number $^{\prime}1^{\prime}$ , three faces each with number $^{\prime}2^{\prime}$ and one face with number $^{\prime}3^{\prime}$. If die is rolled once, determine $P(1$ or $3)$
A bag contains $3$ black and $4$ white balls. Two balls are drawn one by one at random without replacement. The probability that the second drawn ball is white, is
The probability of getting number $5$ in throwing a dice is
The probability of getting head and tail alternately in three throws of a coin (or a throw of three coins), is
Seven chits are numbered $1$ to $7$. Three are drawn one by one with replacement. The probability that the least number on any selected chit is $5$, is
