Understanding Simple Events in Probability Theory: Definition and Calculation

Simple event

A simple event refers to an event that consists of only one outcome or possibility

A simple event refers to an event that consists of only one outcome or possibility. In other words, it is an event that cannot be further broken down into smaller events.

For example, rolling a fair six-sided die and getting a 3 is a simple event because there is only one outcome that satisfies the condition (getting a 3). Similarly, flipping a fair coin and it landing on heads is also a simple event because there is only one possible outcome in this case.

Simple events are often used in probability theory to analyze the likelihood of events occurring. The probability of a simple event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

To illustrate this, let’s consider the example of rolling a fair six-sided die. The probability of rolling a 3 (which is a simple event) can be determined by dividing the number of favorable outcomes (1, since there is only one face with the number 3) by the total number of possible outcomes (6, since there are six sides to the die).

Therefore, the probability of rolling a 3 is 1/6 or approximately 0.167 (16.7%).

In summary, a simple event is an event with only one outcome or possibility, and it can be used to calculate probabilities by dividing the number of favorable outcomes by the total number of possible outcomes.
