When explaining about Independent event we’ll consider two events first and in a space. For example, if those two events are A and B respectively,and they are situated in a space S then they are said to be independent. But remember, if P (AB) = P (A).P (B).

So separate them one by one as:

P(A) = P(A I B) = P(A I B)

P(B) = P(B I A)= P(B I A)

For n independent events A₁,A₂ ,… ,A_n

P (A₁… A₂···A_n) = P (A₁) P (A₂) … P (A_n).
