Final answer:
A simple event is defined as an event that has only one possible outcome. This means that there is no uncertainty or variability in the outcome of the event.
Explanation:
A simple event is defined as an event that has only one possible outcome. This means that there is no uncertainty or variability in the outcome of the event. In other words, the outcome of a simple event is always the same and there is no chance of any other result. For example, if you toss a coin and it lands on heads, the event of getting heads is a simple event because it has only one possible outcome.
In mathematical terms, a simple event can be represented by a single value or point on a sample space. A sample space is a set of all possible outcomes of an experiment. For instance, if we roll a six-sided die, the sample space would be {1, 2, 3, 4, 5, 6}. Each number in the sample space represents a possible outcome of the experiment, which in this case is the number that appears on the top face of the die after it is rolled.
In conclusion, a simple event is an event with only one possible outcome and it can be represented using notation with subscripts and superscripts. It is the building block of more complex events and plays a crucial role in probability theory. Understanding simple events and their properties is essential in solving problems involving probability.
