Question

Suppose we throw a dice once?
(ii)What is the probability getting a number less than or equal to $4$?

Answer 1

When a dice thrown one time we get the following out comes

$S=\{1,2,3,4,5,6\}$

$n\left(s\right)=6$

Let $A$ be event of getting numbers less than $4$ or equal to $4$

$A=\{1,2,3,4\}$

$n\left(A\right)=4$

Probability of getting numbers less than or equal to $4$ is =

$=n\left(A\right)/n\left(s\right)$

$=4/6=2/3$
