CONDITIONAL PROBABILITY Meaning and
Definition
-
Conditional probability is a statistical concept that describes the likelihood of an event occurring, given that another event has already occurred or is known to be true. It is denoted by P(A|B), where A and B represent two independent events.
To understand conditional probability, one must consider the probability of event A happening without any prior knowledge. Then, if it is known that event B has already occurred, the conditional probability refers to the revised probability of event A occurring, taking into account this new information. In other words, it focuses on the probability of A happening under certain conditions defined by event B.
This concept is often used to investigate cause-and-effect relationships or make predictions. By studying conditional probabilities, one can analyze the impact of specific conditions or information on the likelihood of an event occurring. For example, if it is known that it is raining (event B), what is the probability of someone carrying an umbrella (event A)? By examining historical data or conducting experiments, conditional probabilities can be calculated and utilized in various fields such as finance, medicine, and engineering.
Conditional probability is a fundamental concept in probability theory and is essential for understanding more advanced topics such as Bayes' theorem and probability distributions. It provides a quantitative framework to analyze complex situations and make informed decisions based on the available information.

Etymology of CONDITIONAL PROBABILITY
The word "conditional" in "conditional probability" comes from the Latin word "condicio", meaning "a stipulation or agreement". "Probability" comes from the Latin word "probabilis", meaning "worthy of being approved, likely". The concept of conditional probability originated from Thomas Bayes, an English statistician and philosopher, in the 18th century. The term itself reflects the idea that the probability of an event is evaluated based on a particular condition or assumption.
