No of people not from their neighborhood=25-20=5
total contact s=25
therefore probability to call a person not from his neighborhood=5/25=1/5
therefore P=1/5
Is this what you’re talking about
Answer:
Distance between the points=5
Step-by-step explanation:
The distance between two points in coordinate geometry is measured by using the distance formula:
If we have given two points

Distance formula= 
For (0,0) and (4,3)
Distance:

Or
Distance between the points=5
Answer:
