Lecture 24 Probabilities of Independent and Dependent Events

Probabilities of Independent andDependent Events In this section we discuss probabilities of events that occur in sequences of experi-ments There are two possibilities here; either the experiments that we perform donot a ect each other (they are independent) or they do a ect each other (they aredependent)

In particular events A and B are independent if and only if: Pr(A?B) = Pr(A)·Pr(B) Generally independence is something you assume in modeling a phenomenon— or wish you could realistically assume Many useful probability formulas only hold if certain events are independent so a dash of independence can greatly simplify the analysis of a

What are independent and dependent events in probability?

Two Events A and B are said to be independent if occurrence or non-occurrence of one does not affect the probability of the occurrence or non-occurrence of other. If the occurrence of one event affects the probability of the occurrence of the other event then the events are said to be Dependent or Contigent.

How to calculate independent events?

Independent Events: P (A?B) = P (A) * P (B) If A and B are dependent, then the formula we use to calculate P (A?B) is: Dependent Events: P (A?B) = P (A) * P (B|A) Note that P (B|A) is the conditional probability of event B occurring, given event A occurs.

What is the probability of dependent events?

When the outcome affects the second outcome, which is what we called dependent events. Dependent events: Two events are dependent when the outcome of the first event influences the outcome of the second event. The probability of two dependent events is the product of the probability of X and the probability of Y AFTER X occurs.
