Question:
A die is thrown. Find the probability of getting an odd number
Solution:
We know that,
Probability of occurrence of an event
$=\frac{\text { Total no.of Desired outcomes }}{\text { Total no.of outcomes }}$
As $1,3,5$ are odd numbers up to 6 , so the desired outcomes are $1,3,5$, and total outcomes are $1,2,3,4,5,6$
Therefore, total no. of outcomes are 6 , and total no. of desired outcomes are 3 Probability of getting an odd number
$=\frac{3}{6}$
$=\frac{1}{2}$
Conclusion: Probability of getting an odd number when a die is thrown is $\frac{1}{2}$
