The estimated percent distribution of a certain country's population for 2025 is shown in the accompanying pie chart. Find the probability of each event listed in parts (a) through (d) below. **Pie Chart: National Age Distribution**This pie chart illustrates the distribution of age groups within a national population. Each segment of the pie chart is color-coded to represent a specific age range, and their corresponding percentages indicate the proportion of the total population for each group.### Age Distribution Breakdown:- **Under 5 years:** 4.9% (Colored in blue)- **5-14 years:** 12.5% (Colored in red)- **15-19 years:** 5.1% (Colored in green)- **20-24 years:** 6.3% (Colored in lime green)- **25-34 years:** 14.6% (Colored in purple)- **35-44 years:** 12.4% (Colored in dark blue)- **45-64 years:** 25.8% (Colored in teal)- **65-74 years:** 11.2% (Colored in pink)- **75 years or over:** 7.1% (Colored in yellow)The chart visually emphasizes that the largest age group is 45-64 years, comprising 25.8% of the population, while the smallest group is those under 5 years, at 4.9%. This distribution can provide insights into demographic trends and potential societal needs, such as educational services or healthcare requirements.

Continuous Probability Distributions

Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.

Normal Distribution

Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!

Question

The estimated percent distribution of a certain country's population for 2025 is shown in the accompanying pie chart. Find the probability of each event listed in parts (a) through (d) below.

**Pie Chart: National Age Distribution**

This pie chart illustrates the distribution of age groups within a national population. Each segment of the pie chart is color-coded to represent a specific age range, and their corresponding percentages indicate the proportion of the total population for each group.

### Age Distribution Breakdown:
- **Under 5 years:** 4.9% (Colored in blue)
- **5-14 years:** 12.5% (Colored in red)
- **15-19 years:** 5.1% (Colored in green)
- **20-24 years:** 6.3% (Colored in lime green)
- **25-34 years:** 14.6% (Colored in purple)
- **35-44 years:** 12.4% (Colored in dark blue)
- **45-64 years:** 25.8% (Colored in teal)
- **65-74 years:** 11.2% (Colored in pink)
- **75 years or over:** 7.1% (Colored in yellow)

The chart visually emphasizes that the largest age group is 45-64 years, comprising 25.8% of the population, while the smallest group is those under 5 years, at 4.9%. This distribution can provide insights into demographic trends and potential societal needs, such as educational services or healthcare requirements.
