When it comes to making decisions, especially financial ones, understanding the concept of expected outcomes is crucial. In this article, we will delve into the world of probability and expected value, using a real-life scenario to illustrate the importance of calculating expected outcomes.

What is Expected Value?

Expected value is a mathematical concept that helps us determine the average outcome of a situation with multiple possible outcomes. It takes into account the probability of each outcome and the value associated with it. In simple terms, expected value is a way to predict the average return on investment or the average outcome of a decision.

Calculating Expected Earnings for Job A

Let's consider Job A, which offers a 50% chance to earn $3000 and a 50% chance to earn $4000. To calculate the expected earnings for Job A, we need to multiply the probability of each outcome by the value associated with it and then add the results.

Expected Earnings Formula

Expected Earnings = (Probability of Outcome 1 x Value of Outcome 1) + (Probability of Outcome 2 x Value of Outcome 2)

Applying the Formula

For Job A, the expected earnings would be:

Expected Earnings = (0.5 x $3000) + (0.5 x $4000) Expected Earnings = $1500 + $2000 Expected Earnings = $3500

Calculating Expected Earnings for Job B

Now, let's consider Job B, which offers a 100% chance to earn $3500. In this case, the expected earnings are simply the value of the outcome, as there is no uncertainty involved.

Expected Earnings for Job B

Expected Earnings = $3500

Comparing the Expected Earnings

Now that we have calculated the expected earnings for both jobs, we can compare them to make an informed decision.

Job	Expected Earnings
A	$3500
B	$3500

As we can see, both jobs have the same expected earnings of $3500. However, Job A offers a 50% chance to earn $4000, which is a higher value than the $3500 offered by Job B. This means that if we choose Job A, we have a 50% chance to earn more than $3500.

The Importance of Expected Value

Calculating expected value helps us make informed decisions by taking into account the probability of each outcome and the value associated with it. In this scenario, we can see that Job A offers a higher potential return, but it also comes with a higher level of uncertainty. Job B, on the other hand, offers a more predictable outcome, but it is lower than the potential return offered by Job A.

Real-Life Applications

Calculating expected value is not limited to financial decisions. It can be applied to various aspects of life, such as:

Investing: Expected value can help investors determine the average return on investment for a particular stock or portfolio.
Insurance: Expected value can help insurance companies determine the average payout for a particular policy.
Business: Expected value can help businesses determine the average return on investment for a particular project or venture.

Conclusion

Calculating expected outcomes is a crucial step in making informed decisions, especially financial ones. By understanding the concept of expected value, we can take into account the probability of each outcome and the value associated with it. In this article, we used a real-life scenario to illustrate the importance of calculating expected outcomes and how it can be applied to various aspects of life.
