Similarity is that all these processes lead to increase in profit that would further help in increasing per capita income and thus more productivity and better development.

Answer:
Triangulation method
Explanation:
- In triangulation method Scientist s take a paper.
- The sesmometers which are established in that area is shown as green dots.
- The calculated distance from each seismometer to the earthquake is shown as a circle.
- The point where all circles intercept eachother is known as the epicenter of the earthquake.
<u>E</u><u>a</u><u>r</u><u>t</u><u>h</u><u>q</u><u>u</u><u>a</u><u>k</u><u>e</u><u>:</u><u>-</u>
- Their are many plates moving inside earth's surface.
- When the plates collide with eachother a friction arises which is called earthquake.
Probability of an event happening=(numbers of ways it can happen) / (total numbers of outcomes)
P=probability that we are both selected
P₁=probability that I am selected and my brother is selected after.
P₂=probability that my brother is selected and I am selected afer.
P=P₁+P₂
P₁=(1/100)*(1/99)=1/9900
P₂=(1/100)*(1/99)=1/9900
P=1/9900 + 1/9900=2/9900≈0,0002≈0.02%
solution: P=2/9900≈0.02%
