Majority charge carriers in the N-type side of a semiconductor material are electrons, because N-type semiconductor is doped with a material with 5 valence electrons. Semiconductor materials have 4 valence electrons and hold tightly to 8, so there is a "loose" electron for every atom of dopant. Therefore most of the charge carriers available are electrons. IE, electrons are the majority charge carriers.

Minority charge carriers in N-type semiconductor are holes. Only a few holes (lack of an electron) are created by thermal effects, hence holes are the minority carriers in N-type material.

The situation is reversed in P-type semiconductor. A material having only 3 valence electrons is doped into the semiconductor. The semiconductor atoms have 4 valence electrons try to hold tightly to 8, so there is a virtual hole created by a "missing" electron in the valence orbit. This acts as if it were a positive charge carrier. Most of the charge carriers are these holes, therefore in P-type semiconductor holes are the majority charge carrier.

Again, reverse situation to minority charge carriers. Some electrons are loosened by thermal effects, they are the minority charge carriers in P-type semiconductor.

Why transistor is called transistor?

Because in this device the resistance between two terminal respectively collector and emitter is changed by changing the base voltage that is it transfers the resistance between emitter and collector therefore it is called as TRANSISTOR. (TRANSFER OF RESISTOR)
