Express the following probability as a simplified fraction and as a decimal.

If one person is selected from the population described in the table, find the probability that the person has never married, given that this person is a woman.

\begin{tabular}{|c|c|c|c|c|c|}
\hline & Married & \begin{tabular}{c}
Never \\
Married
\end{tabular} & Divorced & Widowed & Total \\
\hline Male & 60 & 49 & 8 & 2 & 119 \\
\hline Female & 58 & 29 & 11 & 8 & 106 \\
\hline Total & 118 & 78 & 19 & 10 & 225 \\
\hline
\end{tabular}

Express the probability as a simplified fraction.

The probability is [tex]$\square$[/tex]

(Type an integer or a simplified fraction.)


Sagot :

To find the probability that a randomly selected person has never married, given that the person is a woman, let's follow these steps:

1. Identify the relevant values from the table:
- Number of women who have never married: 29
- Total number of women: 106

2. Set up the probability:
The probability [tex]\( P(\text{Never Married} | \text{Female}) \)[/tex] is the number of women who have never married divided by the total number of women.

3. Write the probability as a fraction:
[tex]\[ P(\text{Never Married} | \text{Female}) = \frac{\text{Number of women who never married}}{\text{Total number of women}} = \frac{29}{106} \][/tex]

4. Simplify the fraction (if possible):
- In this case, the fraction [tex]\(\frac{29}{106}\)[/tex] is already in its simplest form because 29 and 106 have no common factors other than 1.

5. Express the probability as a decimal:
To convert the fraction to a decimal, divide 29 by 106:
[tex]\[ \frac{29}{106} \approx 0.27358490566037735 \][/tex]

Thus, the probability that a randomly selected person has never married, given that the person is a woman, can be expressed as:

- Fraction: [tex]\(\frac{29}{106}\)[/tex]
- Decimal: [tex]\(0.27358490566037735\)[/tex]

Therefore, the simplified fraction representing the probability is [tex]\( \boxed{\frac{29}{106}} \)[/tex].
