Question

A die is thrown, write a sample space $\left(S\right)$ and $n\left(S\right)$. If event $A$ is getting a number greater than $4$, write event $A$ and $n\left(A\right)$.

Answer 1

When a dice is thrown,
Sample space, $S=\{1,2,3,4,5,6\}$
$n\left(S\right)=6$
Event $A=$ Probability of getting a number greater than $4=\{5,6\}$
$\therefore$ $n\left(A\right)=2$
