Equal probability principle

Hey Guys,

I have got a question.
English is not my first language.

Is the "equal-probability-principle" the same as "the equal-a-priori-probability-postulate"?

Do both names describe the same process?

Thx
Abby

I have not heard the phrase "equal-probability-principle", but I believe that the "equal-a-priori-probability-postulate" refers to the assumption in statistical mechanics that for a system in equilibrium, all reachable microscopic states of the same energy are equally probable.
