probability equations

Let us learn about probability equations

Probability is referred as the branch of mathematics which studies the possible outcomes of given events together with the outcomes' relative likelihoods & distributions. In common usage, the word "probability" is applied to mean the chance that a particular event or set of events will occur expressed on a linear scale from “0” impossibility to 1 certainty, also expressed as a percentage between 0 & 100%. The analysis of events governed by probability is known as statistics.

In a class of sixty students, ten are in the drawing club & fifteen are in the games club. If a learner is selected randomly, what is the probability that the selected learner is:
a) In the drawing club?
b) In the games club?
Probability Equations Solution:
The total number of learner in the class = 60
Number of learners in the drawing club = 10
Number of learners in the games club = 15
The probability of solving that the selected learners in the drawing club is,
P (students in drawing club) = 10 / 60
= 1/6
= 0.17
The probability of solving that the selected learner in the games club is,
“P” students in games club) = 15 / 60
= ¼ = 0.25
