Explanation:
Nitrogen is a naturally occurring element that is essential for growth and reproduction in both plants and animals. It is found in amino acids that make up proteins, in nucleic acids, that comprise the hereditary material and life's blueprint for all cells, and in many other organic and inorganic compounds.

Probability distributions are used to represent data and their probabilities
The table entry is given as:
<u>Age of House Number of Houses</u>
1 15
2 20
3 25
4 30
Start by calculating the probability of selecting a house that has a certain age.
This is calculated as:

So, we have:




This means that the graph that represents the probability distribution must show that the probability of 1 is 0.17; 2 is 0.22; 3 is 0.28; 4 is 0.33.
