The image above represents mean.

To compute for mean, two essential parameters are needed and these are **number of possible outcomes in any single trial (n) **and **probability of success in any single trial (p).**

The formula for calculating mean:

μ = np

Where;

μ = 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

μ = np

μ = (8)(1)

μ = 8

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

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

n = ^{μ} / _{p}

Where;

n = Number of Possible Outcomes in Any Single Trial

μ = 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;

μ = Mean = 15

p = Probability of Success in Any Single Trial = 1

n = ^{μ} / _{p}

n = ^{15} / _{1}

n = 15

Therefore, the **number of possible outcomes in any single trial **is **15.**
