Solution

The science which concerns with probability is known as  
1. Statistics - It is the branch of science and math that deals with the statistical properties of events and their probabilities.

The fall of moisture or water over the surface of the earth from atmosphere is known as  
1. Rainfall - Rainfall is the precipitation in the form of water or moisture. all other options are invalid

The process by which water is lost from the dam reservoir is known as 2. Evaporation - Only evaporation can occur in a dam as the surface of the water is open to atmosphere.

The volume of water stored below dead storage level of the dam reservoir is:  
1. Dead storage   - Beyond this level water shouldn\'t be drawn

The water temperature is dependent on 4. Solar radiation
