Question

A die is thrown. Find the probability of getting:

 2 or 4 

Answer 1

\[\text{ When a die is thrown, the possible outcomes are 1, 2, 3, 4, 5 and 6 } . \]
\[\text{ Thus, the sample space will be as follows }: \]
\[S = \left\{ 1, 2, 3, 4, 5, 6 \right\}\]

\[\text{ Let A be the event of getting a two or four } . \]
\[\text{ Two or four occurs once in a single roll }. \]
\[\text{ Therefore, the total number of favourable outcomes is 2 }. \]
\[\text{ Hence, the probability of getting 2 or 4 is as follows }: \]
\[P\left( A \right) = \frac{2}{6} = \frac{1}{3}\]
