Answer:
![P(W\ n\ F) = 43\%](https://tex.z-dn.net/?f=P%28W%5C%20n%5C%20F%29%20%3D%2043%5C%25)
Step-by-step explanation:
Given
<em>Represent customers that own their homes with W</em>
<em>Represent customers that have lived for less than 5 years with F</em>
Such that:
![P(W) = 60\%](https://tex.z-dn.net/?f=P%28W%29%20%3D%2060%5C%25)
![P(F) = 54\%](https://tex.z-dn.net/?f=P%28F%29%20%3D%2054%5C%25)
![P(W\ or\ F) = 71\%](https://tex.z-dn.net/?f=P%28W%5C%20or%5C%20F%29%20%3D%2071%5C%25)
Required
Determine ![P(W\ n\ F)](https://tex.z-dn.net/?f=P%28W%5C%20n%5C%20F%29)
In Probability:
![P(W\ or\ F) = P(W) + P(F) - P(W\ n\ F)](https://tex.z-dn.net/?f=P%28W%5C%20or%5C%20F%29%20%3D%20P%28W%29%20%2B%20P%28F%29%20-%20P%28W%5C%20n%5C%20F%29)
Substitute values for each
![71\% = 60\% + 54\% - P(W\ n\ F)](https://tex.z-dn.net/?f=71%5C%25%20%3D%2060%5C%25%20%2B%2054%5C%25%20-%20P%28W%5C%20n%5C%20F%29)
![71\% = 114\% - P(W\ n\ F)](https://tex.z-dn.net/?f=71%5C%25%20%3D%20114%5C%25%20-%20P%28W%5C%20n%5C%20F%29)
Solve for P(W n F)
![P(W\ n\ F) = 114\% - 71\%](https://tex.z-dn.net/?f=P%28W%5C%20n%5C%20F%29%20%3D%20114%5C%25%20-%2071%5C%25)
![P(W\ n\ F) = 43\%](https://tex.z-dn.net/?f=P%28W%5C%20n%5C%20F%29%20%3D%2043%5C%25)
