Heya !!
Redox reactions : Those reactions in which oxidation and reduction take place simultaneously, are called redox reactions.
e.g.
1. CuO +H2 -------- Cu + H2O
2. MnO2 + 4HCl -------- MnCl2 + Cl2 + 2H2O
Precipitation reaction : This reaction is also known as double displacement reaction, in which two different ions or group of atoms in the reactant molecules are displaced by each other.
in this reaction a precipitate is produced.
e.g.
Na2SO4 + BaCl2 ------- BaSO4 + 2NaCl
Here , BaSO4 is white precipitate.

Redo reaction -one reactant gets oxidises while other gets reduced during a reaction.Such reactions are called oxidation-Reduced reactions or redox reactions.
Precipitation reaction-A white substance which is insoluble in water is formed.This insoluble substance formed is known as a precipitate.Any reaction that produces a precipitate can be called a precipitation reaction.
For example- Sodium sulphte+ Barium chloride--Baruim sulphate +sodium chloride.
May be it's help u .
Aur woh jo pic de hai woh precipitation ka. example hai dear.
