WebP (A/B) = P (A) and P (B/A) = P (B) and vice versa. If S is the sample space of the random experiment, A and B are any two events defined in this sample space. The two events A and B are said to be independent, that is If P (A / B) = P (A / B’) = P (A) or P (B / A) = P (B / A’) = P (B) and P (AB) = P (A) * P (B) WebAn obvious sample space is S = {w, b, h, a, o}. Since 51% of the students are white and all students have the same chance of being selected, P(w) = 0.51, and similarly for the other outcomes. This information is summarized in the following table: Outcome w b h a o Probability 0.51 0.27 0.11 0.06 0.05 Since B = {b}, P(B) = P(b) = 0.27.
