   The conditional probability is the probability of happening of an event of A given that another event B has already occurred. It is denoted by P (A | B) and it is calculated by the formula P (A | B) = P (A ∩ B) / P (B).

   How to calculate conditional probability?

   • To calculate the conditional probability, we can use the following step-by-step method: Step 1: Identify the Events. Let’s call them Event A and Event B. Step 2: Determine the Probability of Event A i.e., P (A) Step 3: Determine the Probability of Event B i.e., P (B) Step 4: Determine the Probability of Event A and B i.e., P (A∩B).

   Which events are part of conditional probability?

   • The events that are part of conditional probability are dependent events. For example, if we have P (A | B) anywhere in the problem, then it means that A and B are dependent. If two events A and B are independent, then P (A | B) = P (A) and P (B | A) = P (B).

   How do you calculate the probability of a given event?

   • The probability that an event A will occur given another event B occurs is written as P (A | B), meaning “the probability of A given B.” Assuming that the probability of B is not zero, this can be calculated using the formula P (A | B) = P(A ∩ B)/ P(B). Here P (A ∩ B) is the probability of A and B, meaning A and B both occur.

   What is the denominator of a conditional probability formula?

   • The denominator of the conditional probability formula is the likelihood that B occurs. We use that value in the denominator because the chances of event B defines the total sample space. Remember, the nature of a conditional probability is that a given event occurs, and the denominator accounts for that occurrence.

   What is the Kolmogorov definition of conditional probability?

   • These formulas are also known as the "Kolmogorov definition" of conditional probability. Here: Note that the elements of B which favor the event A are the common elements of A and B. i.e. the sample points of A ∩ B. Thus P (A/B) = Number of events favorable to A ∩ B ÷ Number of events favorable to B.

   Why is conditional probability important?

   • Understanding conditional probability is necessary to accurately calculate probability when dealing with dependent events. Dependent events can be contrasted with independent events. A dependent event is one where the probability of the event occurring is affected by whether or not another event occurred.
