How to Calculate and Solve for Mutually Non-Exclusive | Probability

The image above represents mutually non-exclusive.

To compute for mutually non-exclusive, four essential parameters are needed and these parameters are x_A, N_A, x_B and N_B.

The formula for calculating mutually non-exclusive:

P(A or B) = P(A) + P(B) – P(A and B)

Where;

P(A or B) = Mutually Non-Exclusive
P(A) = ^x_A ⁄ _NA
P(B) = ^x_B ⁄ _NB

Let’s solve an example;
Find the mutually non-exclusive when the x_A is 10, N_A is 20, x_B is 5 and N_B is 12.

This implies that;

x_A = 10
N_A = 20
x_B = 5
N_B = 12

P(A or B) = P(A) + P(B) – P(A and B)
P(A or B) = P(A) + P(B) – (P(A) x P(B))
So, P(A or B) = ^x_A ⁄ _NA + ^x_B ⁄ _NB – (^x_A ⁄ _NA x ^x_B ⁄ _NB)
P(A or B) = ¹⁰ ⁄ ₂₀ + ⁵ ⁄ ₁₂ – (¹⁰ ⁄ ₂₀ x ⁵ ⁄ ₁₂)
P(A or B) = ^{10(12) + 5(20)} ⁄ _(20)(12) – (^(10)(5) ⁄ _(20)(12))
Then, P(A or B) = ^{120 + 100} ⁄ ₂₄₀ – (⁵⁰ ⁄ ₂₄₀)
P(A or B) = ²²⁰ ⁄ ₂₄₀ – ⁵⁰ ⁄ ₂₄₀
That is, P(A or B) = ^{(220 – 50)} ⁄ ₂₄₀
P(A or B) = ¹⁷⁰ ⁄ ₂₄₀
Dividing the numerator and denominator by 10
P(A or B) = ¹⁷ ⁄ ₂₄
P(A or B) = 0.708

Therefore, the mutually non-exclusive is 0.708.
