The image above represents the mean. Two essential parameters are needed to calculate the mean: the **number of possible outcomes in any single trial (n)Â **and the **probability of success in any single trial (p).**

**The Formula for Calculating Mean**

Î¼ = np

Where;

Î¼ = Mean

n = Number of Possible Outcomes in Any Single Trial

p = Probability of success in any single trial

Let’s solve an example;

Find the mean when the number of possible outcomes in any single trial is 8 and the probability of success in any single trial is 1.

This implies that;

n = Number of Possible Outcomes in Any Single Trial = 8

p = Probability of success in any single trial = 1

So, Î¼ = np

Î¼ = (8)(1)

Î¼ = 8

Therefore, the **mean** is **8.**

**Calculating the Number of Possible Outcomes in Any Single Trial when the Mean and the Probability of Success in Any Single Trial are Given**

n = ^{Î¼} / _{p}

Where;

n = Number of Possible Outcomes in Any Single Trial

Î¼ = Mean

p = Probability of Success in Any Single Trial

Let’s solve an example;

Find the number of possible outcomes in any single trial when the mean is 15, and the probability of success in any single trial is 1.

This implies that;

Î¼ = Mean = 15

p = Probability of Success in Any Single Trial = 1

Then, n = ^{Î¼} / _{p}

n = ^{15} / _{1}

n = 15

Therefore, the **number of possible outcomes in any single trialÂ **isÂ **15.**

**Calculating the Probability of Success in Any Single Trial when the Mean and the Number of Possible Outcomes in Any Single Trial are Given**

p = ^{Î¼} / _{n}

Where;

p = Probability of Success in Any Single Trial

Î¼ = Mean

n = Number of Possible Outcomes in Any Single Trial

Let’s solve an example;

Given the mean is 4 and the number of possible outcomes in any single trial is 2. Find the Probability of success in any single trial?

This implies that;

Î¼ = Mean = 4

n = Number of Possible Outcomes in Any Single Trial = 2

So, p = ^{Î¼} / _{n}

p = ^{4} / _{2}

p = 2

Therefore, theÂ **probability of success in any single trialÂ **isÂ **2.**
