The image above represents mutually exclusive.

To compute for mutually exclusive, four essential parameters are needed and these are **x _{A}, N_{A}, x_{B}** and

**N**.

_{B}The formula for calculating mutually exclusive:

P(A or B) = P(A) + P(B)

Where;

P(A or B) = Mutually Exclusive

P(A) = ^{xA} ⁄ _{NA}

P(B) = ^{xB} ⁄ _{NB}

Let’s solve an example;

Find the mutually exclusive when the x_{A} is 12, N_{A} is 14, x_{B} is 9 and N_{B} is 17.

This implies that;

x_{A} = 12

N_{A} = 14

x_{B} = 9

N_{B} = 17

P(A or B) = P(A) + P(B)

P(A or B) = ^{xA} ⁄ _{NA} + ^{xB} ⁄ _{NB}

P(A or B) = ^{12} ⁄ _{14} + ^{9} ⁄ _{17}

P(A or B) = ^{12(17) + 9(14)} ⁄ _{(14)(17)}

P(A or B) = ^{204 + 126} ⁄ _{238}

P(A or B) = ^{330} ⁄ _{238}

Dividing the numerator and denominator by **2**

P(A or B) = ^{165} ⁄ _{119}

P(A or B) = 1.386

Therefore, the **mutually exclusive **is **1.386.**
