An event that includes one and only one of the (final) outcomes for an experiment

What is the probability of Choosing Red Ball From Box that Fill With Red ,Green , Blue and Black Balls

Event

… rule is applied to compute the probabilities of events for an experiment for which all
outcomes are equally likely.

Classical Probability is applied to compute the probabilities of events for an experiment for which all outcomes are different.

Ten of the 200 randomly selected cars manufactured at a certain auto factory are found to be lemons. Assuming that the lemons are manufactured randomly, what is the probability that the next car manufactured at this auto factory is a lemon?

If an experiment is repeated n times and an event A is observed f times, then we use ..

Subjective probability is the probability assigned to an event based on subjective judgment, experience, information, and belief.

Subjective probability is assigned arbitrarily.

Conditional Probability probability of a single event without consideration of any other event.

Conditional Probability is the probability that an event will occur given that another event has already occurred.

is also called simple probability

if p(A) = 5 , p(B) = 25 , P(A Union B) = 125 , P(A Intersection B) =25 then P(A| B) =

P(A|B) = P(A) : dependent

cannot occur together

Two events are said to be …. if the occurrence of one does not affect the probability of th

if A , B are Independent Then P(A | B) =

P(A) + P(A’) = …

P ( A or B) =

random variable is a variable whose value is determined by the outcome of a random experiment.

random variable that assumes ...... values is called a discrete random variable.
