Step-by-step Solution
To determine if the set \( S \) contains an irrational number, we need to identify which numbers in the set are irrational.
Given set \( S \):
\[ S=\left\{-0.6,-\frac{1}{4}, 0,1 . \overline{3}, \pi, \sqrt{13}\right\} \]
We know that irrational numbers are real numbers that cannot be expressed as a simple fraction. They are non-repeating and non-terminating decimals.
Let's identify which numbers in the set \( S \) are irrational:
1. \(-0.6\) is a rational number because it can be expressed as \(-\frac{3}{5}\).
2. \(-\frac{1}{4}\) is a rational number because it can be expressed as \(-0.25\).
3. \(0\) is a rational number because it can be expressed as \(\frac{0}{1}\).
4. \(1.\overline{3}\) is a rational number because it can be expressed as \(1 + \frac{1}{3}\).
5. \(\pi\) is an irrational number because it is a non-repeating and non-terminating decimal.
6. \(\sqrt{13}\) is an irrational number because it is a non-repeating and non-terminating decimal.
Therefore, the set \( S \) contains two irrational numbers: \(\pi\) and \(\sqrt{13}\).
Quick Answer
The set \( S \) contains two irrational numbers: \(\pi\) and \(\sqrt{13}\).
