Introduction

In probability theory, the sample space is the set of all possible outcomes of an experiment. When we have multiple events or trials, we need to consider the combined sample space, which includes all possible outcomes of both events. In this article, we will explore the concept of a combined sample space and list all the elements of the sample space for a given experiment.

The Experiment

The experiment consists of two parts:

Spinning a Spinner: A spinner with four equal sections labeled 1, 2, 3, and 4 is spun.
Tossing a Dime: A dime is tossed.

The Sample Space

The sample space of an experiment is the set of all possible outcomes. For the given experiment, we need to consider the possible outcomes of both spinning the spinner and tossing the dime.

Spinning the Spinner

When the spinner is spun, there are four possible outcomes:

1: The spinner lands on the section labeled 1.
2: The spinner lands on the section labeled 2.
3: The spinner lands on the section labeled 3.
4: The spinner lands on the section labeled 4.

Tossing the Dime

When the dime is tossed, there are two possible outcomes:

H: The dime lands heads up.
T: The dime lands tails up.

The Combined Sample Space

The combined sample space is the set of all possible outcomes of both spinning the spinner and tossing the dime. To find the combined sample space, we need to consider all possible combinations of the outcomes of both events.

List of Elements of the Sample Space

The list of elements of the sample space is as follows:

(1, H): The spinner lands on the section labeled 1 and the dime lands heads up.
(2, H): The spinner lands on the section labeled 2 and the dime lands heads up.
(3, H): The spinner lands on the section labeled 3 and the dime lands heads up.
(4, H): The spinner lands on the section labeled 4 and the dime lands heads up.
(1, T): The spinner lands on the section labeled 1 and the dime lands tails up.
(2, T): The spinner lands on the section labeled 2 and the dime lands tails up.
(3, T): The spinner lands on the section labeled 3 and the dime lands tails up.
(4, T): The spinner lands on the section labeled 4 and the dime lands tails up.

Conclusion

In conclusion, the sample space of the given experiment consists of 8 elements, each representing a possible outcome of both spinning the spinner and tossing the dime. Understanding the sample space is crucial in probability theory, as it allows us to calculate the probability of different events and make informed decisions.

Discussion

The sample space of a combined experiment can be quite complex, especially when dealing with multiple events or trials. However, by breaking down the experiment into individual events and considering all possible combinations of outcomes, we can determine the combined sample space.

Example Use Case

The concept of a combined sample space can be applied to various real-world scenarios, such as:

Medical Trials: In medical trials, researchers may need to consider the combined sample space of different treatments and patient outcomes.
Financial Analysis: In financial analysis, the combined sample space of different market trends and economic indicators can be used to make informed investment decisions.
Engineering Design: In engineering design, the combined sample space of different component failures and system outcomes can be used to ensure the reliability and safety of a system.
