![**Probability Problem**
**Question:**
What is the probability that the person selected owns a smartphone?
**Options:**
1. 46/100
2. 64/100
3. 70/100
4. 46/64
5. 18/64
6. 64/70
---
**Explanation:**
When calculating probabilities, the formula used is:
\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}} \]
By analyzing and solving this problem, you can better understand how to determine probabilities, which is a key concept in statistics and probability theory.
**Choice Analysis:**
1. **46/100**
2. **64/100**
3. **70/100**
4. **46/64**
5. **18/64**
6. **64/70**
Consider each of these probabilities and evaluate which fraction correctly represents the likelihood of a person owning a smartphone based on the provided data or given context.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbd964ba9-d764-4d26-a421-54f1f9939a38%2F0cd5b67d-5772-435c-be21-49887575fa9a%2Fpr52nwm_processed.jpeg&w=3840&q=75)

Transcribed Image Text:**Survey of Smartphone Ownership**
100 people were surveyed and asked if they own a smartphone. A person is selected at random from the survey. Here are the survey results.
| | Female | Male | Total |
|--------------------------|--------|------|-------|
| Owns a smartphone | 46 | 24 | 70 |
| Does not own a smartphone| 18 | 12 | 30 |
| **Totals** | **64** | **36** |**100** |
**Explanation of the Data:**
The table summarizes the responses from the survey:
- 46 females and 24 males reported that they own a smartphone.
- 18 females and 12 males reported that they do not own a smartphone.
- In total, 70 people own a smartphone, and 30 people do not own a smartphone.
- The survey included 64 females and 36 males, adding up to 100 respondents overall.
These results illustrate the distribution of smartphone ownership among the surveyed population and how it varies between females and males.
