How to Calculate and Solve for Certainty | Probability

The image above represents Certainty.

To compute for certainty, one essential parameter is needed and this parameter is Total Number of All Possible Outcomes (N).

The formula for calculating Certainty:

P(A) = x N = N N


P(A) = Certainty
N = Total Number of All Possible Outcomes = 2

Let’s solve an example;
Given that the total number of all possible outcomes is 2. Find the Certainty?

This implies that;

N = Total Number of All Possible Outcomes = 2

P(A) = x N = N N
P(A) = 2 2
P(A) = 1

Therefore, P(certainty) is 1.
