Question
Hi! I need help on this problem that was presented on my Stastistics class please
Transcribed Image Text:The graph of the discrete probability below represents the number of live births by a mother 46 to 51 years old who had a live birth in 2017.
**Graph Explanation:**
- **X-axis:** Number of Live Births (ranging from 0 to 8)
- **Y-axis:** Probability (ranging from 0.00 to 0.35)
**Probability Values:**
- 0 live births: 0.239
- 1 live birth: 0.251
- 2 live births: 0.169
- 3 live births: 0.112
- 4 live births: 0.097
- 5 live births: 0.036
- 6 live births: 0.041
- 7 live births: 0.041
- 8 live births: 0.055

**Questions:**
1. **Find the mean and standard deviation of the probability distribution. (Round to three decimal places.)**
2. **What is the probability that a randomly selected mother 46 to 51 years old who had a live birth in 2017 has had her first live birth in that year?**
3. **What is the probability that a randomly selected mother 46 to 51 years old who had a live birth in 2017 has had her at most second live birth in that year?**
4. **If a mother 46 to 51 years old who had a live birth in 2017 is randomly selected, how many live births would you expect the mother to have had? (Round to one decimal place if needed.)**
