Why conditional probability is different from common probability?

Conditional probabilities arise when you revise the probabilities previously attached to some events in order to take new information into account. The revised probabilities are 'conditional on the new information you have received'.

A probability based upon an event that has already occurred?
May - or may not - be a conditional probability. A conditional probability is not becessarily chronologically structured.
What is the probability of tossing four coins and getting four heads if the first two tosses are heads?
The conditional probability is 1/4.
What do experimental probability and theoretical probability have in common?
They are both measures of probability.
How do you find the probability of an event followed by another event?
If the events are independent then you can multiply the individual probabilities. But if they are not, you have to use conditional probabilities.
What is the conditional expectation function?
It is the integral (or sum) of the joint probability distribution function of the two events, integrated over the domain in which the condition is met.
A probability based upon an event that has already occurred?
May - or may not - be a conditional probability. A conditional probability is not becessarily chronologically structured.
What do I call a probability that is based upon an event that has already occurred?
It can be called a "conditional probability", but the word "conditional" is irrelevant if the two events are independent.
What is the relationship between conditional probability and the concept of statistical independence?
If events A and B are statistically indepnedent, then the conditional probability of A, given that B has occurred is the same as the unconditional probability of A. In symbolic terms, Prob(A|B) = Prob(A).
The probability of event A occurring given event B has occurred is an example of?
The probability of event A occurring given event B has occurred is an example of conditional probability.
What is best graphical method for calculating joint and conditional probability?
Tree diagram
What event is it whose probability depends on one or more event?
A conditional event.
What is an examle of conditional probability?
The probability that, if I get caught by a red light at one set of traffic lights, I will get a green at the next lights is an example.
What is the probability of tossing four coins and getting four heads if the first two tosses are heads?
The conditional probability is 1/4.
What is the most common word that signals a conditional statement?
The most common word that signals a conditional statement is "if." It is used to introduce a condition that needs to be met in order for a certain action or result to follow.
What do experimental probability and theoretical probability have in common?
They are both measures of probability.
Out of a standard 52 card deck what is the probability of drawing a heart given that a red card was drawn first?
This is a conditional probability, given the card is red, what is the chance it is a heart. Since there are 2 red hearts, the probability if 1/2
How do you find the probability of an event followed by another event?
If the events are independent then you can multiply the individual probabilities. But if they are not, you have to use conditional probabilities.
