What is an event in mathematics?

Answer 1

An Event is a set of outcomes in a given expirament

say, were talking about independent events, that's when event a does NOT effect event b. where as if we were talking about dependent events event a DOES effect event b.

dependent event example- a teacher draws a name and DOES NOT put it back. and chooses another.
