Question
A two digit number is formed with digits 2, 3, 5, 7, 9 without repetition. What is the probability that the number formed is
a multiple of 5 ?
a multiple of 5 ?
✓
Answer
Probability that the number formed is an odd number,
$\begin{array}{l}
p ( X )=\frac{\text { Favourable outcome }}{\text { Total number of outcomes }} \\
\therefore p ( X )=\frac{1}{5}
\end{array}$
$\begin{array}{l}
p ( X )=\frac{\text { Favourable outcome }}{\text { Total number of outcomes }} \\
\therefore p ( X )=\frac{1}{5}
\end{array}$
