The image above represents success and failure.

To compute for success and failure, two essential parameters are needed and these parameters are **x **and **N.**

The formula for calculating success:

**P(success)** = ^{x }⁄ _{N}

Where;

x = Number of successes

N = Total Number of Trials or Items

Let’s solve an example;

Find the success when the x is 12 and N is 14?

This implies that;

x = Number of successes = 12

N = Total Number of Trials or Items = 14

**P(success)** = ^{x }⁄ _{N}

P(success) = ^{12 }⁄ _{14}

Dividing the numerator and denominator by **2**

P(success) = ^{6 }⁄ _{7}

P(success) = 0.857

Therefore, the **success **is **0.857.**

The formula for calculating failure:

**P(failure)** = ^{(N – x) }⁄ _{N}

Where;

x = Number of successes

N = Total Number of Trials or Items

Let’s solve an example;

Find the failure when the x is 12 and N is 14.

This implies that;

x = Number of successes = 12

N = Total Number of Trials or Items = 14

**P(failure)** = ^{(N – x) }⁄ _{N}

P(failure) = ^{(14 – 12) }⁄ _{14}

P(failure) = ^{2 }⁄ _{14}

Dividing the numerator and denominator by **2**

P(failure) = ^{1 }⁄ _{7}

P(failure) = 0.142

Therefore, the **failure **is **0.142.**
