A probability distribution shows all the values a random variable can take together with their probabilities, as a table, graph, or formula. For a discrete variable the probabilities must sum to one.
It lets us predict how likely each outcome is and calculate expected results.

Where it appears in Add Math
You meet Probability Distribution in the Probability Distribution chapter of SPM Additional Mathematics. Knowing the term precisely matters in the exam: questions often hinge on reading a keyword correctly, and because SPM marking is analytic, using the right definition in your working helps secure method marks.
Our teachers make sure a student can not only recite what Probability Distribution means but use it fluently in a full solution.
The term in three languages
Because the SPM Add Math paper is bilingual (BM/EN), it helps to know this term in each language: Probability Distribution (EN) · Taburan Kebarangkalian (BM) · 概率分布 (中文)
