alleryConditional probability P(A | B) is defined as:
AP(A and B) / P(B) (with P(B) > 0)
BP(A) - P(B)
CP(A) × P(B)
DP(A or B)
Answer & Solution
Correct answer: A. P(A and B) / P(B) (with P(B) > 0)
P(A|B) = P(A and B) / P(B).
Probability of A given B has occurred.
For independent events, P(A|B) = P(A).
