Use the data given in the table below to compute the probability that a randomly chosen voter from the survey will satisfy the following. Round to the nearest hundredth.

The voter is between 39 and 49 and is registered as a Republican.

| Age | Republican | Democrat | Independent | Other | Total |
|-------|------------|----------|-------------|-------|-------|
| 18-28 | 205 | 432 | 98 | 112 | 847 |
| 29-38 | 311 | 301 | 109 | 83 | 804 |
| 39-49 | 250 | 251 | 150 | 122 | 773 |
| ≥ 50 | 272 | 283 | 142 | 107 | 804 |
| Total | 1,038 | 1,267 | 499 | 424 | 3,228 |

To solve the problem of finding the probability that a randomly chosen voter from the survey will be aged between 39 and 49 and registered as a Republican, we can follow these steps:

1. Identify the total number of voters: The total number of voters surveyed is given in the table, listed under the "Total" column.

[tex]\[ \text{Total number of voters} = 3228 \][/tex]

2. Identify the number of voters who are between 39 and 49 and registered as Republicans: From the table, the number of Republicans aged between 39 and 49 is specifically mentioned.

[tex]\[ \text{Number of Republicans aged 39-49} = 250 \][/tex]

3. Calculate the probability: The probability [tex]\( P \)[/tex] that a randomly chosen voter is aged between 39 and 49 and registered as a Republican is calculated by dividing the number of Republicans aged 39-49 by the total number of voters.

[tex]\[ P = \frac{\text{Number of Republicans aged 39-49}}{\text{Total number of voters}} \][/tex]

[tex]\[ P = \frac{250}{3228} \][/tex]

4. Perform the division: Calculate the division to find the probability.

[tex]\[ P \approx 0.07744733581164807 \][/tex]

5. Round to the nearest hundredth: To obtain the final answer, round the obtained probability to the nearest hundredth.

[tex]\[ P \approx 0.08 \][/tex]

Thus, the probability that a randomly chosen voter from the survey will be between 39 and 49 years old and registered as a Republican is approximately 0.08.
